Does cutting down the muffler cause any performance issues like back pressure or anything? I hear of people doing it and it looks good but I wouldn't want to screw with the performance in a negative manner or cause it to be overly loud.

I love that popping sound when slowing down. If I remember it's uneven back pressure but don't hold me to that.

Does it still pop on decel? My guess is that it would, because blockoff plates would have more of an effect on decel pop then the length of the slip-on.

I agree aBout cutting it down but it looks like the cf is flared on both ends. And yes it still pops and no the block off plates have not been done. I also have no tune, do I need a pc3?

A PCIII wouldn't hurt, but I would do a poor mans blockoff first. Just get under the tank and block the lines needed with rubber caps and hose clamps.

With a PC3 you can pull fuel out of the 0% column at certain RPM's and the POP is completely eliminated.
Yep. Though kind of a band-aid fix, that's what dynojet tells you to do. Though if you're going to dyno tune the bike, every good tuner blocks the AIS so they get accurate AFR's.

Link is for 3rd gen, but very similar on all gens. Keeps clean air from entering the exhaust (burns last little bit of fuel for emissions reasons), which is what ignites to 'backfire' most the time on decel (most the time - assuming you don't have another bigger problem).

In any case, the pipe looks great. I would cut it down though.

Well I took a hacksaw to my brand new exhaust.



Happy Now? J/k.
