My dad wants to get an aftermarket exhaust for his 98 GT. Its completely stock as it sits. I told him to look at the Magnaflow cat-backs... there were two kits on summit, one with a narrow, cylindrical muffler and the other with a standard looking muffler. What are the diffferences between those kits?
Should we look at replacing the cats while we're down there as well?
Thanks
