How to: Suzuki M50 "Honest Abe" Exhaust Mod

[@kyoskei]

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

[@robertmeasmer1139]

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.

[@farooqkhan3729]

Thanks - I was looking for some such validation before embarking on this mod.

[@robertmeasmer1139]

@Farooq Khan hey I know my post is 4 years old. So let me update this alittle. It did cause it to run stronger butbit also caused a little back firing. But nover broke down.

[@jawzsome]

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 !!!

[@GiorGarrocho]

So.... 6 Years later, do you still have the same bike? How does she works now?

[@yushienshiah8382]

So how's it running?!?

[@handyshawn2866]

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 .

[@doe12341]

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

[@tooljst8]

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

[@Marc_Wolfe]

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.

[@rogerscott8321]

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.

[@jamiewisener812]

U r right tyler. My service guy gold me the same thing. He said u can completely gut it if u want to with no I'll effects. Change ur intake is a different matter.

[@bamaboysmith2723]

Awesome to hear this.i was about to buy a fuel commander after removing the outer baffles

[@Gazeroni]

I have done a couple dramatic conversions to exhausts, and if the back pressure changes dramatically enough, you would require a rejet/remap. But with something like this I am with you...the difference is negligible. I think really what it comes down to is that your bike should tell you if something is off. If this mod results in the sound you were after and it doesn't cause issues like: discolored plugs, overheating, deceleration popping, gold/blue pipes or power surging on hard decels, then enjoy!

[@randall1959]

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.

[@ChrisG3253032]

I've got a '08 suzuki VL250LC, has a big single pipe. I initially drilled 6 10mm holes. In the end I cold chiseled the whole end plate out. Gave it a bassy note, loud but not too loud. Has a light burble on downshift but doesn't backfire or crackle. I haven't retuned, and there's no sacrifice of power. I've had it up to around 125kp/h a couple of times.

[@randall1959]

@@ChrisG3253032 There are always going to be some bikes that relieving the back pressure actually improves performance.

[@jamesmcgrath1952]

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.

[@scottdurbin9684]

Yeah it's me. Ditto

[@Truthofstillness]

The C50 doesn’t sound just fine(In my opinion). I own one and it’s barely heard on the road, and definitely not heard while sitting at a light. That why I’m watching all these modification videos for C50 exhausts. Guna try out some holes, then the backplate and if that ain’t enough..cobra it is.

[@Momokahn]

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.

[@jonneet2126]

Steve Copeland Steve, have you had any problems with the shaft drive system? I understand there is a seal which may allow water in and cause a lot of rust.

[@markbrush8927]

Wow! -Great achievement! I love my 2015 c50t! Much happiness since riding again after 25yrs. I'm liking this cheap, easy mod. Thanks, again.

[@dtov26]

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.

[@hotthreads]

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

[@kv1206]

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.

[@TheWolfmanG]

politicalobservor 1 the Boulevard M50 surprisingly uses fuel injectors; not carbs. Damn thing is more like a car then a motorcycle. But it sure is a smooth idle/ride.

[@johnakaODB]

Will this work on the S83 boulevard

[@jacobwatkins4695]

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?

[@torkrench]

Debaffle doesnt do anything on newer ones with converters.

[@cactusstudiossouth]

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

[@GeoffreyVansickle-rt4wi]

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

[@jamesnico4412]

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.??

[@latauladelpoblelatauladelp9255]

Muy bueno Hermano 👏 👍 👌 🙌 💪 😉 👏 👍

[@chriselliott.4996]

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

[@sandrider1406]

The sound will change but not power as you will need to remap the ECU for fuelling and open up your air box intake. .

[@bosdad7]

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

[@7aric]

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

[@ecletronic]

somewhere japanese enginers cry looking to this...

[@moneyhauler1]

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?

[@RicoRico202]

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

[@hotthreads]

Yep. It will work on any bike.

[@TheWolfmanG]

0:30 vs 6:10

[@BoY860]

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

[@BoY860]

+2wheelpiracy i ended up shortening the ends of the pipes and shortened the baffle, then i bolted it from the underside and it sounded perfect. Didn't sound cheap weak or rattling. but sold the bike fun while i had it for a little bike.

[@chriselliott.4996]

Heard cobra muffler sound really nice almost a Harley sound

[@bosdad7]

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

[@RITBlake]

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

[@bosdad7]

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 !!

[@TheMotorcycleGuys]

You actually can lose power if you don't rejet. If it's carbureted, there's a good chance it will run significantly richer and affect the air/fuel mixture through the rev range.

[@nathandurkee770]

Dexter exhausts don't breath? You breath in and out correct? Air intake brings air in, exhaust brings air out. The better air flow in and out the more performance you get. But this does sound like crap. Buy an aftermarket exhaust.

[@johhnyo]

so you re jet and open the breather..not a big fix..better than the stock

[@TheHirevs]

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

[@44357514]

On Fuel injected bikes you have to electronically / computer change the settings for the fuel injectors.

[@rickg.5171]

Did the same thing to my Sportster years ago.

[@flash6357]

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

[@andrefpereiraalves]

I dont think adding the 4 holes would make a difference if you dont punch the plates, or does it?

[@henkbroersma175]

Thanks works perfect and the sound is very good

[@farooqkhan3729]

Did you observe any issues in performance, back-pressure, or fuel consumption after this mod? Thinking of doing it. Any tips appreciated - thx

[@Randomaction93010]

Very good! Very lean approach!!!

[@8307c4]

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.

[@jawzsome]

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

[@Mrtweet81]

Obviously no need to thank him...

[@wozza400]

Great thanks , will do the same

[@111JasonShaw]

Awesome idea!!

[@Pharoyar]

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

[@kevinhardy8263]

hi thats what i intend to do on mine leave the end plates alone

[@TheRetroBen]

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

[@bamaboysmith2723]

Wrong..long as you leave the the intake stock it effects nothing but the sound

[@warmongerairsoft]

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

[@michaelrauch495]

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

[@iraklipapava9333]

I just drilled and it was jerking on takeoff , so I closed holes ..

[@BushmasterRaZ]

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.

[@ronfullerton3162]

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.

[@mattmichelewoodworth8400]

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

[@drewkastelic6154]

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

[@louisvilaros9066]

I think its sounds good

[@klavdy]

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

[@xtreme7386]

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

[@ganonpig]

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.

[@farooqkhan3729]

Hey - how did your mod go? Is there any difference observed in engine performance or fuel consumption after de-baffling?

[@ganonpig]

@@farooqkhan3729 Honestly I can't say for sure anymore, considering I sold the bike almost a year ago. From what I remember, performance and fuel consumption seemed to stay about the same. The only thing you'll really notice out of a mod like this is a deeper engine tune. Could be wrong though, who knows, maybe it did give me a few extra horses and I didn't even notice. lol

[@riceburnerbiker1483]

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.

[@Alienated420]

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

[@QFour]

What did it do to your gas mileage?

[@NOTadribabe]

I did the same thing but without the four holes... no effect on mileage... if anything it may have gone up a tiny bit because i was idling lower because i liked how the bike sounded at lower rpms haha

[@ChadPayne13]

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

[@Buelligan88]

It sounds terrible.

[@ChadPayne13]

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

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

[@SuperCyril2]

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

[@johhnyo]

the original pipes sound like a singer sewing machine..so who cares if they are destroyed..piece of s**t anyways. debaffling the right way can make a big difference on how the bike sounds.

[@chriselliott.4996]

[@qjg8888]

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.
