Hats off to Rusty and all the fine folks at D&D. I had a set on a sport bike back in the late 90s and they have always been competitive. Thanks for highlighting a good ole US of A company.

I commented on your last video telling you I run the SE Stage 4 kit with the Zipper's 472 cam. Glad you went with the same cam. I made 120/130 and it feels like a beast at any rev range.

Back in the day (late 90's) I had the opportunity of attending a high-performance motorcycle school (I'm intentionally being vague) and shortly thereafter purchased a dyno and traveled the country testing motorcycles. I was amazed at how illiterate most heavy cruiser riders were regarding torque vs horsepower. Your man there at D&D did exactly the right thing and your M8 on the dyno is proving that. Early torque and sustained HP through the run. High airflow and a tuned exhaust system put the "icing on the cake". Well worth the cost!!!!

D&D is the best out there for Harley baggers I think. Some others may have better sound or better looks but no other exhaust offers it all like D&D does. Glad you worked with them so more people out there can know who they are.

The quality and attention to detail with D&D wins hands down. Even how they pack up their stuff for shipping is superior than a lot of other companies. Extremely happy with their stuff.

D&D sound is amazing! Money well spent!!! Here in Italy now is 2019 so I can say happy new year to All the Americans! Buon Anno! Ciao!

I have the same cam and exhaust in a 124. 132hp/145 torque. Makes 140 torque at 2500 rpm. The D&D Billet Cat is the best performance exhaust on the market. I ran 2 other exhausts on the build and finally broke down and bought the D&D. It is expensive but worth every penny! Tell Rusty him doing this video with you sold at least one header lol.

You should really do the Oil Pump upgrade from S&S. It'll help with cooling and reduce chances of a breakdown with high performance parts.

D&D is the best out there. Love their work

Adam, retired Vet from San Antonio. I am going to reach out to these guys to see what they can do for my 2016 Pro Street Breakout. Thank you brother and Happy New Year...Aaron

D&D really is above and beyond the rest. I had baffle-less drag pipes on my 06 FXSTI and Arlen Ness big sucker with a tune. Changed exhaust to D&D FatCat and retuned. It literally feels like a different bike and it’s just a little old stock 88”. Quality of the pipe is absolutely second to none.

IMO Zippers is one of the best cams and the tuner he added is top shelf , just those two items would have made a big change and the cat free pipe is a plus

Wow, that’s a hell of an improvement in torque, that’s where you’re really going to feel the difference, great cam choice and D&D exhaust!

Kinda sounds like you might have been happier with a Stage 2 or 3 instead of the 4, due to the fact those actually have more torque than Stage 4 in the lower RPMs. Regardless, this new setup kicks ass!

HD offers different cam options for their Stage IV build kit. Adam’s power cam builds torque at high revs. HD’s torque cam option builds max torque around 3K. My Stage IV M8 with the torque cam dynoed at 118 lbs of torque at 2900 rpms and runs flat to redline. I had it dyno mapped, and installed HD’s dynamic tuner. It runs awesome. Very smooth power, and excellent low RPM ride-ability. The big difference is in the pipes. I have V&H head pipes and mufflers. You can keep your warranty and have performance. The aftermarket exhaust does not void your warranty, as long as the exhaust doesn’t cause engine damage.

Very nice numbers and a large improvement. This is what I was hoping to see. Great video Adam.

Now you are going in the right direction! Get rid of that Screamin' Eagle cam. That is top end.That Redshift 472 is a great midrange cam. You will feel more torque at lower rpm's The Thundermax is a very smart move also. Great product! You will be pleased with the rideability of your scoot now! Remember when I told you, you wouldn't like that top end cam? You will like that Redshift though. I've seen people time and time again look at that HP number and never give a thought to where the HP or Torque come in, and the dyno graph they show you on paper is at wide open throttle. No other throttle position between closed and WOT. After people ride for a while they realize they screwed up! It bothers me people allow Harley to hand them BS, so to sell their product. Harley don't care! It's all about the money! You want to spend it, they will gladly take it. Now you down 2,298.90 for telling Harley you want a fast bike with high HP. They guide you to the most expensive upgrade and tell you it's FAST!!! lol Bunch of crooks! Anything high performance, you much better off going Zippers, Fueling, S&S, Wood Performance or Andrews and find you a guy like Rusty to set you up. Screamin' Eagle Products SUCK!!! And so does Harley service. Yea, I know, the Waranty! Wait till it expires. Just put a breather pipes and a tuner.

Ill give it to D&D. I believe they make the best pipe around. A little pricey. But definitely worth it!

Thanks De&D. You just made my 2019 even better with my new exhaust project.

Love D&D bought them at lone star rally in 2018

Bike sounds great and the torque line is excellent... Things (regardless of what it is) put together properly is KEY! Indiana way...2006 FXSTSI... 95” flat top piston Stock springs/values Ported heads and decked .050 to get 10-1 compression Bassani 2-1 road rage (would love a d&d but these were 250.00 on Craigslist) Screaming eagle heavy breather And the key with this, Andrews tw 54 cam, .555 lift I wont post numbers because wouldn’t be believed, but WOW, ... Absolutely correct about using power where you ride at...

Wow, that was just unbelievable what you had done to that bike. Really impressed with D&D. Wish they were here in NC. That was a great video.

D&D simply the best pipe all around,great vlog Adam

Another great video Glad Rusty explained the difference in dyno numbers

Those pipes seem to be made the same way as my Squeeks Big Twins out of Murphysboro, IL. I have them on my Deuce on youtube. Good job man! It sounds great!

Thanks for making this video. It’s good practical information on upgrades that are not potentially sales driven. It help with ideas for my future upgrades. I’d like to see a future video on how you like the thunder max ECM compared to what you had before. I just did a stage 1 using the both the Harley tuners, but once the extended warranty has expired I’m looking forward to maximizing the engine potential for how I want to ride.

Awesome video as always adam. Rock on. Have a great New Year

Look out, hes about to drop that 116 in the indian now. D&d makes that pipe for them now and loydz is your guy for cams. Rock on happy new year thanks for sharing the helpful info for the consumers on twos

What is the weakest link in the build? The four piece pressed together flywheels. If you put a big bore kit, and higher compression would be even worse. Harley should make a solid forged crank with side by side connecting rods, and you could go to town. I enjoy your channel!!

What a great flat torque curve for that bike and driving style. It's going to be a ball.

Love it man!!! We ran DnD on our sportbikes for years and years!! Awesome company for sure!!

That's why I originally didn't want the stage 4 kit cause I wanted to torque quicker than at end of power band. The is a quy her in NY Hulton speed he does a nasty setup with those zipper cans also

You can get all of those parts at Zippers Performance . I don’t work for them but they’ve been around for a long time and make great performance kits for all Harley’s.

A year later and I’m still watching this video. Rusty is a badass. I thank him for his service. I am also going to buy one of his pipes. Texas Made baby!

Nice upgrade max torque starting at 2500. sweet. Rubber side down and let the miles roll on. bnb said your going to be at IMS in Dallas for a meet and greet. wish I could be there.

That idle sound is amazing! Great video

Have D&D 2-1 Billet cat exhaust on my bike. I didn’t add the ghost pipe.

Great video, Adam. Definitely gonna check out D&D when I go from stage 2 to stage 3. Also, like that you make a point to talk about usable Hp and Tq .

Love the channel and this video. I have a 22 road glide 107 and already have the billet cat with bb baffle. Best exhaust imo hands down. Had the fatcat on my 15 road glide too. I wanna do the same as this video and I live 20 miles from D&D. Maybe rusty can cam swap me too

Great parts with a good tuning device. Doing it right

Man, that exhaust sounds good now!

Man it sound good watching it online cant wait to hear it person, hopefully going to make it back up in March

Just sub'd. I already have the Thundermax (not yet installed), been saving up for exhaust and was leaning toward D&D, but you just made up my mind. Thanks for the breakdown and the 100% honesty.

Sounds great. With great gear like this you would have thought they might smile once.

I have that same exhaust on my m8 107 and it's great. Awsome sound great low end torque. I also have a ventilator intake and cycle Rama 460 cam. Great combo

Yeowzaaaaa brother!!! Good job Rusty!!! Now for the little Honda, lol? Papa Greg here👍😎👊

That is sick! No interest in getting the stage IV but the cam and pipes sure warmed up the soul of your bike and put the torque where it needs to be.

Thanks. can't decide between street glide or dark horse. M8 making that power is it.

Wish you had just replaced the tuner, retuned, and dynoed again. I’m sure the HD tuner was holding the numbers down. Bike sounds great and the torque curve is impressive!

great bike. good goals, however I have a 2009 yamaha stratoliner, 4 valves per cylinder, welcome to that harley, 96hp, 126 torque at 2800 rpm, stock motor, K&N air filter, D&D slip on.

Glad to see the Harley Adam.

Holy sheetrock! That bike sounds so sick!

Excellent love the lights more as I love better fuel mileage for distance but great info

Bike sounds great. Happy New Year to all y'all from TN.

That's one good sounding M-8!!!

Happy New Year, Adam have a great ‘19 and be safe with all that new HP.

Best sounding M8 out there !

That sound is just fantastic!!!👍🍺

Man that is awesome. I bet his business will boom now.

I’m way late to the party 4 months past. I would of loved to have seen your original setup and just change to D&D. Then went to zippers cam and thundermax. I have to believe that the D&D scored you the biggest gain. I’m not saying that the cam and tuning didn’t add more but Rusty’s pipe make Tq early and continue throughout the power ban.

I know it's hard to cover all different combinations. I bought my 2017 street glide and put in the Woods 222. It made so much difference it isn't even funny. I gutted a stock pipe, added a decent air cleaner and tuned it through all the throttle settings and rpms. I think I tune as well as any and a hell of a lot better than most. I use Technoresearch. I've been tuning bikes for about 8 years. Most tuners set WOT only and never even look at the mid and lower settings. I have no idea if a 472 cam would help or not but it would so minimal it's not worth the trouble You also have a big CI engine here and I left mine 107. This is a great video and I know it was a lot of work. I don't plan to do anything to my bike.....further. I'm gettin 42 MPG and it's got a HELL of a lot more power than it did stock. If you can feel a couple ft lbs of torque or hp then you're a better man than me. The dyno might show a couple and you might pull me a half a bike length here and there but pretty much any cam will make a huge difference....and the rest is all in the tune.....by the way...Cyclerama has a really great performing cam....they're all good...and the difference between the boltins is really minimal....I wanted reliability and power so no goin in the engine for me other than the cam

Have been reading great things about 2-1 D&D exhaust. Just ordered one for my 19 RG. Doing a S&S 475 and ThunderMax. Nice winter project!

great to see you back on a Harley !

Adam very good informative vid down from the change in HP and Torque to the difference in price. 👍🏽

Sounds Amazing & Looks like its worth every penny i might be Looking to do More Upgrades Thanx 😎

That mechanic is the man

I want to support D&D Exhaust.

I have D&D 2 into 1 fat cat on my 2015 SGS.. And I Love it!

Happy New Year. Be safe. Hugs to all three of you😍☃️😎🏍🇺🇸

Great video Adam thanks for sharing brother ride safe..

Zippers cam what Is what I install in my customer's bikes. It looks like I now have a new exhaust system to recommend to my customers.

Great sounding bike .. you are going to bring in the new year the right way .. Happy New Year's to you and Ashley...

love your comparisons on the scratch paper cool upgrade

Now that's a neighbor hater system if I ever heard one!! And a 20% Power gain across the board is a lot. That would be approximately 40-50 hp and torque on my old Silverado. D and d does it good with talant to spare.

That’s the best sounding m8 I’ve heard since they came out.

Man I’m so glad to see you get rid of that screamin chicken junk. D&D rules !

Listen zippers is the best hands down

Hell yeah you can here a big difference. Question? What software do you use for video editing. Im such a noob but love to shoot videos.

That was interesting thanks for sharing that video

I’m always looking for video that provides good info. Good work brother 👍

Thanks for this Adam !

I love my D&D billet exhaust

That's bad ass Adam,sounds better as well,be safe on that rocket!

HAPPY NEW YEARS TO U-ALL IN TEXAS

Now your talking worthwhile upgrades. Is your bike no longer emissions compliant with this setup? Not that I really care about that. This man definitely knows his shit. Great video.

Happy New Year Texas!! Good stuff Adam. I’m sure there will be a follow up review. Looking forward to it. Speaking of Texas...Curious how the good folks at Paris Harley Davidson are doing these days. Have not seen anything on them for a while.

That’s a big gain for just a couple changes. Great vid!

I just want a better sound for my M-8...i live in Dallas no f-ing way am i able to use any more power than stock. To dam congested ...even on road trips to much dam traffic...just want that rumble 107 is fast enough

That’s why you go stage 3 over stage 4. Low end torque earlier.

A very well explained vlog, some good work there. All the best for the New Yr👍👍😎

Wish you had a side by side sound comparison. It sounds and looked faster for sure.

Damn good video brother! Probably the truest and most informative dyno video I've seen, including cars. Hope to see you again soon at the Fastlife campout coming up!

Hey adam. I see you got more POWER. Theres no dust on the bike. Lol

Love Zippers stuff too.

Great video as usual but I want to compliment the owner on his confident composure and outstanding technical grasp on quality and details. Well done guys...

Looks and sounds good rocking a 2017 dyna lowrider with magnaflow exhaust and fp3 tuner really want to change cams next and then get a dyno tune any suggestions where to get a good dyno tune in Oklahoma or Texas

“Does what it’s supposed to do.” That’s what we’re all looking for.

Sounds a lot better for sure

Enjoy it brother, nice mods

How much was the labor charge ?
