exause sounds are diffirent and the times are 0:20 - 3:30 - 6:12 Up vote for everyone else

Thanks for the Tip on this Modification. I just did this to mine, its sounds great now. I used the Rod from a horseshoe game set, the cast iron style horseshoes. the rod is solid steel. worked great .

well I just did it on my 2007 c50 and it sounds and runs great I even feel better throttle response even in high gear as far as over all performance, will have to see over the long run .but right now im very pleased with the results:) thanx ABE !!!

It's their bike, they can do what they like. Nice video. Thanks for sharing this mod.

I have Cobra pipes, but this is cool, cheap and sounds good. Thanks for tips

Did this to my 2005 c50 runs amazing and sounds mean. No loss in power or problems with fuel so far. So all the people on here stating that it will mess up the engine. What's your facts to back up your claim? I just see the results and been running like this for about 2 months. No issues. And I run it hard.

Literally sounds broken. Reminds me of a Jeep that came into the shop with a rust hole in the header. Thanks for helping us not make that mistake.

Very good! Very lean approach!!!

somewhere japanese enginers cry looking to this...

60,000 miles on my 2009 M50 SE. Debaffled at about 5,000 miles. No other mods, no power commander, no nothing. To all of the exhaust experts, when can I expect my bike to blow up from doing my the debafflingthe of my exhaust? I also average right at 50 mpg on my bike that has yet to blow up.

Thanks works perfect and the sound is very good

Awesome idea!!

you don't have to rejet because it is fuel injected. from everything I've read, you don't have to remap because you're not changing the air/fuel mixture. there is no more exhaust coming out than there was before, there is just less there to silence it. the only time remapping will be needed is when you upgrade to a more free flowing air filter.

Great video. Just a quick question, after inserting the steel rod I see that I need to pierce through two plates on the upper muffler. How many plates will I need to pierce through on the lower muffler? Thank you and I appreciate your response.

I used a small round file to de-burr the holes after I drilled them. -Thanks for watching!

I have a 2010 kawasaki vulcan nomad with stock pipe thinking of doing as per vedio, as all its founction are electronic, was wondering before i do the debaffle by punching through wil it damage my system being fuel injectored.??

My stock pipes on my C50 sound just fine the way they are. Actually, if you hear them in person the stock pipes have a surprisingly moderately loud low rumble. It's just that unlike a Harley's uneven rumble the Suzuki C50's rumble is steady and even.

How does this mod effect the back pressure and cylinder valve intake?

Great thanks , will do the same

I prefer this method over just drilling out the end of the muffler. You actually want to keep some of that back pressure so you don't have to change the carburetor jets. You can also tune for the sound you want. Loud is fine as long as you don't sacrifice performance. And there is such a thing as too loud.

When you drilled the holes in the back, how did you get the edges of your drill spots so smooth?

Heard cobra muffler sound really nice almost a Harley sound

My question though is that when I looked inside the exhaust it looks like it goes down to another opening so what does this do?

Chad did you have any problem with popping when decelerating on the road ?

Yes agree does sound a little more throatier but again as someone mentioned below to get the best performance is to re jet carbs with stage 2 kit.

Muy bueno Hermano 👏 👍 👌 🙌 💪 😉 👏 👍

I'm lost, is this suppose to give it more power? Because the sound is not that much different.

Debaffle doesnt do anything on newer ones with converters.

Yep. It will work on any bike.

Wow...nice...this can be done to a c50? Same year..

When you smacked the bike I about cried brother lol :)

Idea use be taking baffles out for less back pressure more horse power. If it's sound buy right stuff these bikes are tuned for certain amount back pressure

very nice. better than drilling the entire plate out and leaving a raggity hole

I think its sounds good

Will this work on the S83 boulevard

Did this modification require rejetting as it would if you added an aftermarket exhaust? And are the baffles in the rear section of the pipes so I could buy a used set and change them out?

could this be done too a 2007 c50 as well? thanx in advance for your reply

Do you think a home depot will have a steel rod like this? Thats perfect just need to find something to puncture the holes

Great Video, Thanks! Very informative and to the point.

Just did this on a 03 I picked up. Fingers crossed…

Great work . . . just piercing the plates would work for me. Will do that on mine.

I wonder if the 4 holes will burn out after awhile…..,

Did the same thing to my Sportster years ago.

так и сделаю себе !5+за видос!

0:30 vs 6:10

I removed the baffles on mine, this looks easier, too late though.lol nice vid

Hey, I have a honda GL500 that I'm rescuing from the junk yard. Will this work on my bike? Also... What's the importance of spiking through? Wouldn't just drilling the 4 holes suffice for sound purposes? I mean seems like the spike penetration is where you'd lose performance if any. Back pressure and all.

I used to do that when I was young but I found it doesn't make the vehicle faster, it does catch attention (definitely some unwanted), and you can plan on buying new mufflers sooner than if you had left it alone.

one size does not fit all on exhaust mods. Do some testing before and after a modification like this, and then you will know. Time the time needed for the bike to run through the rpm range that you use. I have a Volusia Suzuki, later called the C50 that shared the power plant with the M50. And in the case of these bikes, I would time fifth gear acceleration from 50-70 mph. Do eight to ten runs, make the mods fast and do eight to ten runs again. doing it quickly will keep variables such as temperature, humidity, wind, and such close enough so as not affect your results. If it takes longer to accelerate after than before, you need to rejet or remap. Every aspect of engine tuning is a science. But this mod simply reduces back pressure, and you may get by with current settings. But start changing tube sizes and lengths, different bends, adding more cylinders to one pipe, and other changes from stock, and you will of opened up a whole new can of worms. Testing your bikes engine performance before and after will be your best answer for your situation.

I wonder what just the 4 holes added would sound like.

do you understand that when you take away any back pressure from the engine by opening the exhaust you also need to re-jet youre carbs? or it will run to lean and you will burn out the valves

Thought it sounded pretty good after mod. Bunch of people wining oh here though. Few have any idea what they are talking about. Do what you want to your bike. Hell I built a bike that has straight pipes. screw em

Nevermind the haters on this thread! That's what you get sometimes for trying to help people. Where did you get your steel rod?

Increased a lil. Prolly because I was rolling on the throttle a lil more. LOL

I did this as a temporary solution and I have lost a ton of power . Did anyone else have this problem? I have a 07 fuel injected c50

What did it do to your gas mileage?

Why not just use a hole saw like guys do on their Honda’s?

It could just be the audio quality but I couldn't really tell much of a difference. I'm currently in the process of de-baffling my stock exhaust on my C50 Boulevard. It's possibly an even simpler mod. just use a 3" and a 1.5" hole cutter saw to remove the backing plate at the end of the baffle, then use a broom stick or some small rod to wiggle the baffle until it breaks free from the tack welds. I removed 1 baffle and am currently just waiting for my only battery for my drill to recharge before doing the bottom one. LOL. I can already tell it's gonna sound way better afterwards. For once my pipes will be loud enough so the dumbasses around me will actually know where I am so they don't hit me.

Home depot, in the building materials section

ups!:)

I got lucky and had the original owner buy my cobra pipes.. they sound off like your trying for. HD is loud and three times more expensive then it should be. Good bikes, but ridiculous priced and crazy to get paid repairs. All for the sound. I got enough sound on my after market exhaust (cobra) I got 3 valves per piston, Equivalent HD has 2......96cu.in. HD is drastically over rated.

LOL unbelievable !!!!!!

👍

Instructions unclear now I have a muffler sticking out my ass. Wtf

Lol. It was a $3 bit. Part of a $9 3pc set from Harbor Freight.

Se escucha igual que desgracia no hubo. Cambios

Sounds the same to me

I just drilled and it was jerking on takeoff. terrible. , so I closed holes , don't do this..

OK till it comes to the MOT

To all the people that said you would loose power doing this,,, Your WRONG. the better a motor breaths the better it preforms. this is why race cars don't use mufflers !!

Why would you want to ruin a set of pipes, decrease performance and have it sound like crap?

what a hack job!

Not at all. Just a lil on the top end. Maybe 2%

Stock sounded fine now it sounds like shit and the fuel map is off.

Против лома... нет приема... (русская поговорка)

I guess nobody told you "slow speed heavy feed"while drilling - way to burn up a 50$ step drill

nice pipes Jethro ,,,,wtf

Don't be so cheap and go buy some cobra aftermarket barkers. You just destroyed a perfect set of original pipes.

Now to rejet your carbs.

Louco!

It sounds terrible.

this is so reneck! mess up a perfectly good exhaust. That can never be fixed

And you lose all your back pressure and it sounds cheap buy some real pipes and save the life of your engine.

I like crap.

Please don't do this to your bike. Save up for slip on or a full exhaust and remapping or carb adjustment. Yes race cars don't use mufflers but their fuel is managed accordingly.

You lost a lot of power doing that

You should Not do some cheapo modifications on a Nice bike that costs a reasonable amount of Money. If you go get an old Honda 350 for $100. then go ahead and try this.

Jetzt bist der Chef auf der Straße.... 🙈.. Das sieht hässlich aus und klingt total schlecht. Dann lieber Original.

Хрень, было лучше

please don't do this, the sound will be gone within a month, you will loose POWER! it will run like ehhhh
