spintech
I have a set of 3" Sportsman XL's on my 521ci Ford and I love them... They are built very tough. They're a bit noisier than i expected (sounds great though) and they don't have the annoying drone inside the car that many performance mufflers do. I'm really glad I ditched my Flowmasters for Spintechs and I plan to put a set on my Cuda when the time comes.
