2007 ZX6 With dual two brothers
 

I put a down payments on a 2007 zx6 with Dual Two Brothers exhaust I'm guessing the pipe suppose to fit a 2006 636 It fit under the bike but one piece of plastic nder the rear seat is not quit right. Does anybody know if this pipe will hurt or hinder the perfomance of the bike Please help

Welcome to KF. I am trying to picture that plastic under the seat in question. Congrats on the new ride.

post some pics when you can

post a pic of the platic you are talking about...

It's the flat blick plastic that comes to a V well v creased in the center. The plastic is what goes around the stock exhaust. It is a 2 piece plastic that they took apart at the rear it is still connected under the surround painted black Cowl I'll try to get pics this week

how does she run?

If you're asking if a piece of plastic is going to effect the performance of the bike u are loco in the cabeza..

If you're asking if the pipe will effect the performance it depends on the setup.. but if it's aftermarket I doubt it's harming it in anyway.

From what I have read, I think the only way to really be sure, would be to run the bike on a dyno and have a look at the printout. If the bike is snapping and popping, or back firing, or if it seems to bog down on take off, getting it re-mapped to the exhaust will make a world of difference. If the only concern you have is that the pipe is slightly pushing out on the plastic body panel, but is running fine, I think you will be fine. It's either the result of an amateur install, or a " that's close enough" type of attitude by a hasty mechanic. Sounds like a great bike, and a nice exhaust system though! Good luck with it, and I look forward to seeing pics!
