I don't think there are any cons except the sled is louder. Some might call that a plus too though!
lol


no hp gains on the 600,only on the 700. no jetting required,it will just be a about 4db's louder thats all you will get out of doing it.

I did all 3 TY mods to my '99 600 triple all at the same time (reed notch, exhaust hole, and head gasket). I left jetting stock, never had any issues at all, though I've never ridden in temps colder than minus 5 F. I'd say that it definitely runs better, but not so much in HP, rather in ez starting, warm up, and throttle response. It takes the gas instantly now when I blip the throttle. She's probably leaner with the pipe punched out, but that's ok by me. It seemed too rich B4 and plugs are still chocolate brown. Do it!

The silencer mod sounds great! Just did it to my Dad's - he's 61 and loves it!

I did it to mine the other night and I think it sounds pretty good. It seems like it's more responsive now too but maybe I'm imagining things.

No, I think it helps them out quite a bit - my dad's is quick now.

Silencer Mod?
What is involved with a silencer mod??
I have a stock can and would like to have it sound a bit better.
I do have a Bender can that I bought used and love the sound, but when I have it on my sled makes some pretty funny popping sounds in the pipe
Love to try the silencer mod though
