Cat Delete?

I have a 08 R6 (newer style) and I was looking to delete my Cat and replace it with a mid pipe. I have a competition werkes gp exhaust and stock headers. I also do not have a power commander (or anything like that). I was wondering if it would be bad for my engine or power. I have heard different things, like I'll lose all my back pressure or it will mess up my bikes computer. Does anyone have any experience with this and on top of that have any recommendation on mid pipes, I have found a few. But I don't want to get one that will breakdown on me.

Thanks in advance!

Re: Cat Delete?

Muffler delete......the catalyzers are in the headers. And yes removing the muffler will drastically affect the exhaust flow. You will need to tune the bike to get rideabity and performance gains.

I find a Soap Box comes in handy to get on my High Horse!

Im sorry, I am new to this site. Didn't mean to come off as lazy, just ignorant of something new to me. I will do some more digging.

Re: Cat Delete?

Everything you need to know should be in this thread: M4 is probably the preferred y-pipe maker here on the forum.
