^^^I'm with this guy^^^
I did it a little while back and I'm still happy with it. Haven't noticed anything different with it.
5 Min Exhaust Mod....
Thanks Guys...I did read these threads...So I ended up doing the mod...It does sound better I used a 3/8" extension (big side) to make the hole so about 1/2" Diameter in the pipe.
I am still thinking about opening the hole larger, it is lower but I would like to see if I can get a little more out of it.
I think I am going to try to open it up as close to the outer pipe as possible
Thx

altering the muffler should [edit] NOT affect emissions
muffler does what its name says, muffle sound

Stock, there should NOT be a hole. The stock pipe curves down right after it goes into the can. Looks like someone already punch the hole through it for you.i'm curious, i just looked inside the tailpipe and saw that there was already a hole there. now is there not supposed to be one at all?

h i victor, I did this too, a few days ago... I'm wondering if you have had any bad effects from doing this?
I couldn't tell you for sure since we don't have bike inspections. This mod is only really putting a hole through a single piece of pipe that has nothing in between it where it bends into the can from the outside. No catalytic converter, no baffles... It would be really hard for someone to tell that you did something to the exhaust. Mine looks completely stock. The sound is deeper, but really not much louder, so it wouldn't really be noticeably that something was done.
However, all this said, I take NO responsibility for your actions.
Sorry to bring back an old thread, but I just finished this.
I didn't go larger than a nickel size with a pipe. I used a flat head, turned it in the hole as the metal isn't that thick, then used an socket extension, then a small pipe.
Way more throaty at start up and under acceleration, zero noticeable perormance issue, besides all you're doing is diverting some exhaust gas into the box.
I recommend for the guys looking for sound until they feel comfortable dropping 500+ on exhaust.
I'll post the video ASAP.

Just did this mod. The hole is roughly 70% the size of the stock outlet. I definitely notice a better sound at idle but not as much of a difference when I rev it at idle. Haven't had a chance to ride it yet as it's dark and below freezing temps right now but I'll take it for a ride tomorrow. i'm thinking I'll open up the hole even more after I test it out on a ride. Happy so far with the outcome!
So what is the verdict of the majority, this mod or this

I have spare exhaust for experimentation.
