Stock exhaust Mod

Hey all, I did some searching, and saw i guess a couple ways of punching out the baffle on the stock exhaust. One guy just drilled some holes in the bottom of the can almost like just an exhaust leak. Then the other guy actually shoved a bit down into the pipe itself and punched some holes in the baffle. I'm just curios as to which method is more widely used and will sound the best for now at least until I can get an aftermarket exhaust system. I know there will be no if any performance increase. I would just like a lil more sound !!!!!

Also if you have anything to add as far as exactly how to go about this that would be great also. Sorry to beat this mod to death, and thanks in advance.

Trust me, punching holes in your baffle does nothing but ruin a stock exhaust that you can no longer sell when you end up purchasing an aftermarket one.

if you really want to

i am assuming when you say baffle you are referring to the catalitic converter
it is located just below the rear slip-on part of the exhaust right as the exhaust turns to go to the front of the bike. if you want to get rid of that DO NOT DRILL HOLES IN THE OUTSIDE OF THE EXHAUST take the rear passenger peg off, pull the can and down pipe off bike, and get you a long, good sized screw driver and a hammer and knock that honey comb looking thing out. (it isnt easy but it can be done --- but make sure that you are not beating a hole in the side of the exhuast pipe--- once you get it ALL out start the bike up and pray that all the pieces come flying out of the exhaust. they should i have done it for a few of my buddies. you should hear the exhaust change tone once all the stuff is out. do one last visual check just to double check. put everything back together.
performance wise- this does nothing
sound wise- a little deeper but not much

once you get it all out then you need to hope that your state doesnt go to emissions testing on motorcycles. :icon_lol:

Baffel and Cat are two entirelly different things. The baffel is the suppressor in the exhaust can, itself.

Leave your Cat alone.

Ok, if you are looking for more sound, and aren't too picky about what kind of sound you can mod the stock can. Anything you do, punching out the baffles from the outlet, or drilling holes will increase the noise it makes. There is also a thread on here that shows a guy cutting the can in half to remove the baffles. You're only going to get about $40 for that stock can when you go to sell it.

I punched like 10 holes in my baffle, just because I wanted a change in sound. It does change it a little bit. Seriously it's not like you can get much for your stock exhaust anyway, and most of us poor college kids will get slipons as soon as the $$ comes in. No big deal.

I took like a 18 inch screwdriver and a rubber mallet and punched holes all through it.

Hi again...

in the exhaust system, there are two baffles: One baffling in the Catalytic Converter, and then the baffling in the silencer. depending on which way you look at it, the "Secondary baffle" would be the baffles in the Silencer.

Primary exhaust baffling = catalytic converter
secondary exhaust baffling = silencer

I'm not quite sure what your friend said either...

Thank you, I'm not sure either, this is the first sport bike i have owned and is the first time i have ever done research into "modding" them. I am used to cars, and just for the record i am mechanically inclined i just dotn like undertaking a task before i know what im doing. that being said i didnt quite understand what he said either thats why i was posting up here......I understand now about poking the holes in the pipe....is that all that is done, i belive what my buddy was saying is he actually physically pulled something out of the can itself along with poking the holes...that was the step i am now fuzzy on.

Thank you ;)

well if it's a silencer he was talking about, the tubes and fiberglass is what he would have removed.

Ebay has about 5 or 6 stock cans right now so if you mess yours up just buy a new one for about 35-45 dollars.
