HOLY SMOKES! I have a 475C in my 107 with Bassani 2x(1)x2 Header and CFR Slipons and my TQ curve looked exactly like that. Now I see why my Tuner said I needed another exhaust or baffles. YIKES

Smartest man I’ve seen in this industry. Sure wish I lived close to his shop……..

I spoke with Dave last year and explained what I wanted. I ride a street glide with the Rockford system. He recommended the "quiet" baffle. These baffles sound great and are by no means quiet. It’s a perfect sound. If anyone is wondering if they are to quiet, the answer is no. It won’t completely drown out the Rockford system and has plenty of bark! Dave did a cam and a couple other things on my bike. The results were absolutely amazing. Still can’t get the smile off my face. Thanks again Dave This is the place to bring your bike!

WOW ! I always understood that baffles were important however, never realized how much it can change and alter the results. That was pretty cool the way you demonstrated that for us. Awesome Dave I really enjoyed it. Thank you.

nice presentation

Thanks Dave for a very informative video

Great video. We appreciate you sharing knowledge with us. Keep the videos coming🤙🏾

Dave starring in Mythbusters! Thanks Dave. This is great info for everyone.

Dave is doing my cam in April. He convinced me to change my Tab zombie baffles to the louvered baffles. I just changed em over and glad he did a video to show the reasons why he recommended I make the change. I allready noticed I got some torque back from when I did the head pipe and tune. The tab louvered baffled are quieter at idle but still rip pretty good under acceleration. Cant wait for him to work his magic in April

Fantastic information thank you for schooling us Dave very much appreciated!!

Great testing and video ! Thanks for your work

Great info Dave!

Good work, Dave!

Good episode thanks for sharing your data

Outstanding info !

Another fantastic video

Dave how about an episode on throttle body sizing and proper throttle mapping

Great video Dave. Ill always use louvered baffles. I biught the tab mufflers with the zombie baffles in them. My road king suffered crazy low end loss with them. The zombie bafflesnare completely smooth woth only the slightest tapering towrds the back of the muffler. That was wasted money ill never get back. They do have louvered baffles but the pipes cost me 750$ woth the zombies and i wasnt spending anymore on baffles. Went back to my bassani rr3 stainless pipe.

I have the 117 with the S&S 475 cam along with the 4.5" Khrome Werks slip ons with the quiet baffles. On the dyno i am running 124 hp with 136 torque.

a picture is worth a thousand words. . So my fatboy 107 with screamin eagle 2 - 2 has probably the best low end tq setup ?

I have a m8 127. I had 2 1/4 baffles. Runs strong but so quiet. Decated head pipe. I just for fun had some baffles and changed the core to 2" straight pipe core. And it actually made it not just a tad bit louder but more crisp. Torque is a tad bit more also from seat of the pants feel. Wot it's almost loud, loud. I'm nervous to say, hey this is ok. But let's see some work done to baffles that shrink a tad and have no holes lol. My vrod had a destroyer exhaust with a fake cone as a baffle. This is what let to the insane idea I did.

Love the content. Subscribed👍🏻 what’s your thoughts on using a 2-1-2 head pipe combined with kw mufflers with either baffle? I hear people like to use a different head pipe

I have seen for the m8 motor having baffles works best. I have the same system on my twin cam 103 and Khrome Werks told me don’t run a baffle for the 103. What’s your thoughts on this? Thanks love all the videos!

Great video. I switched to that “spoon” baffle (HP+) from the louvered, and I felt it pull harder from a dig on my 124”

Have you compared cat vs no cat? I've been curious about this recently. I have s&s sidewinder 2 into 1 with a short baffle and love the sound. I was wondering if I should leave the cat or remove it. I live in california so reduced heat would be a plus.

Nice job--thanks---Just wondering how the TABS would perform?

How do you feel about the fuelmoto Jackpot M8 Street Outlaw Chrome Slash Down Slip On Mufflers?

Baffling !!! LoL

I’m having the Fueling 465, and these pipes put on as we speak. I didn’t even think to order different baffles. Will I need to retune if I add the quiet baffles later? I have the Thundermax tuner so maybe it can auto tune the change?

Great video but what is the mod exactly that you do to the spoon baffles? I don't beleive you told us. Watched the video 3 times lol

What about a khrome werks louvered baffle with a reducer

Does the spoon side go up or down? Or does it really matter?

Have any results on Khrome Werks 2-2 vs 2-1-2 header?

Will I get the same performance with the hideaway header? Or is the aggressor a lot better?

Thanks Dave, very informative. Was the modification to the spoon baffle raising the spoon up 1"? You are really knocking it out of the park with your videos.

Excellent and informative video proving the theory that proper back pressure is key to getting maximum hp and torque out of the M8. I have the 2 - 1 - 2 exhaust on my RG. I was curious why you chose the 2 - 2 since many say that the 2 - 1 is better for performance. Is there any proof that the 2 - 1 would get better hp and torque numbers over the 2 - 2, or the 2 - 1 - 2?

the spoon has it!

Those are Kromewerks "Performance Baffles"

Love this video,but I'll be nice if the numbers be visible....very hard to read ...Thank you

Did I miss it? What are those head pipes?

Hey Dave... I have a 131 build with Woods 22XE CAM and Rhinehart slimline duals. I am thinking of switching cams to Fueling 508 or 521. Which do you think I should select for my build or do you suggest changing something to get more low end and horsepower?

Dang David. I gotta get rid of my 2-1 and go with a Khrome Werks.

Hi Dave are the S&S grand national mufflers good with a fuel moto head pipe jackpot 2/1/2. With a 22XE cam with the mufflers I listed or do you recommend different

Khrome werks or nothing.

The ripper baffle only cleans up the sound at high rpm, no power gain. The performance baffle works best if you cut half the spoon off.
