i have ther SVT dual exaust on my zetec, and it sounds way better tyhan you might think, it doesnt have the angry bees sound or anything, i dont even have a resonator on it and the only time it rasps is when it shifts and when the engine is warming up. if i would put new mufflers on it it would be Dual DTM style mufflers with the curved tips running up the bumper...that would be hott!
