Has anyone replaced there mufflers with flowmaster 40 series. If so did you have to do any modifications. I bought a pair and 3 local exhaust shops in my area refussed to install them, claiming they will not fit. :eek:

I have a pair of the super 40's on my 04, I got the 3 in and 3 out with both outlets to one side of the muffler, it was tight but they did go up there. I also cut out the resinator chambers and it really sounds good.

I bought the mufflers, they welded them on, and put the Magnaflow tips on....IMO they look better than stock!! :) Sounds way better also! I don't believe they make a bolt on kit yet...

Dave :cheers
