Cool Exhaust modification

Quick question, Ive read on here that a few have drilled a stock exhausts' baffel. Anyone know exactly how this is done. Or does anyone have pics of this being done?

Thanks:

I started to do this the other day, but after drilling for 5 minutes and barely making a scratch I said the hell with it.

You can do it like the link above or you can find someone that can weld and put this on the end of a rod and get drilling!!!! Something to get you by, but doesn't compare to an aftermarket..

Did you punch a pilot mark. That usually helps with drilling into tough metal

Don't drill the holes in it. Just take a long crow/pry bar or long screw driver stick it in the muffler and knock a hole in the baffle. You cant see the hole that way.

A little bit louder at idle a good sound when your getting on it.. You will get used to it after a week or two.. It will get you by until you get an aftermarket..

To me it sounds perfect. I think all the aftermarket exhuasts I have heard are too loud. I bought a 3/8" drill bit for drilling titanium from Napa and went home and drilled. It sounds like a quiet aftermarked pipe. I'm so glad I did this instead of spending a retarded $400 on a tiny pipe. BTW, somebody is getting rich off of these things, see how much they costs compared to a cars exhaust w/ the amount of material factored in.

BTW you dont even need a drill, infact i just used a punch and punched a hole in the can, the used a screw driver to make it larger. I was realy supprised by the sound, not bad at all. Not as loud as the slipon ive been using for the past year, but it has a claner sound. I know what some of you are thinking.. No my method didnt make the can look like crap, infact my holes are clean, and smooth around the edges :-P Thanks for the reply to my posting, it was much appreciated!

I would just be worried about metal shavings falling into the pipe, I know air is blown out but I can see some chunks just rattling in the exhaust if they don't come out. Any ideas on this?

I did it, its easy all you have to do is get a 13or longer inch drill or you can use a short drill with the extension u can buy it at wall mart (use the short drill with the same grip tip as screwdriver tips tip so it wont be round otherwise you can't use extension).put it inside the canister and start drilling holles. Start with a smaller drill finish with a big one dont use too small you might brake it. After that accelorate few times to blow them metal chips out you'll tell the differents right away. to me exhaust sounds great way better then it was

Is there a difference between drilling holes INTO the can(like on the website) or just drilling/punching a hole INSIDE the can(like CBR/LS1 did)??

It would be great if someone could post a sound clip.. I'd lean more towards drilling a hole inside the can, so exhaust isnt leaking out of two holes on the side of the pipe.. rather straight out of the pipe like it's supposed to.

I did the hole inside mine long ago. I'd be happy to put a sound clip on here if someone would want to instruct me how! I have a digital camcorder. Just not sure how to link it to the site. Once I know how, I'll make one and post it asap!

This seems like a nice mod however, wouldn't you fail emissions when that time comes around cause of the holes in the muffler? I am not dogging on this at all, but on inspection they would say that it needs to be fixed, I guess you could wrap with exahust tape or something when taking it to the inspection station.

I drilled the hole when the bike was running and gave it some gas when the bit went through.. Never heard any rattling inside when I was done...

man thats not a good idea to have your bike running all the fumes inside your lungs????? you can die, man thats not good shut it off and then start it up when you are done and blow it out with the the throttle or use magnet stick it in and youll get most of the metal chips out, i did it both ways

i just did this mod, and I like the way it sounds for how much it cost (nothing).. anyways, i also just installed a set of PP. I noticed the tires got pretty hot after 6 miles of night time riding. Is this due to the 2 holes I drilled which is facing straight down to the tire or is this just how PPs get? I guess my question is if it due to the drill, will this shorten the life of the tires significantly since it's getting stickier?

your tires should be fine unless your melting them lol, as far as the heat goes, put your hand down there and let it run and see.... i mean how big is the hole? its pretty far away and your tire hugger should cover some of it?.... I never have felt my tires after running them... If there is direct heat... make sure the tires dont dry out thats all if that can even happen with that brand.

lol.. thanks for your input.. no, they 're not melting, but they do get really warm.. i don't remember my pilot sports getting this warm while riding at night.. the hole i drilled is 3/8.. i didn't really follow the directions from the mod direction, so instead of drilling where it angles, i drilled it where it's flat.. and it's closer to the rear than the hugger.. oh well, my rs-5 is coming in within the next 2 weeks.

There is a link to a thread with video and sound of a guy who did this. Before and after clips I will see if I can find it and post it here.
