From downpipe all the way back with resonator, mufflers, and choice of tips....if possible...all stainless steel.......lifetime warranty??? i think about 1500 is not so bad. Stainless headers for a V8 are a grand alone. i figured with a turbo car, the HP and TRQ gains would be better. i am sure with the XEDE it would be. For 1300 dollars, however, the XEDE would be my first upgrade.
