Just to give you another option on exhaust choices......I went a different route. Don't think you "have" to go with magnaflow just because most do. I wasn't too happy with the magnaflow sound. I wanted a deeper growl so I chose to go with a hooker aero chamber muffler. A lot of GN guys run this muffler and it sounds great! I spent hours on youtube listening to various mufflers and decided on this one. Here are some pics of the install. 3inch stainless catback provided by BDJ (resonator removed) with a 1 in 2 out hooker aero chamber muffler. The tips are 3 inch oval borlas.
