buy the ATS upgrade exhaust for the 94 factory turbo trucks.for 800 bux youd figure they'd have used a decent way to clamp the downpipe to the outlet housing.i thought i was gonna get more turbo whistle but instead i get a system that leaks worse than a 3" gash in a truck tire!!!the stupid little twisted bracket they supply to bolt the downpipe to something dont work cuz the damn tranny dipstick tube is right in the freakin way!!!!!the tail pipe dont fit,it hits the frame,rear fuel tank and the springs!!if i didnt cut the stock downpipe in 3 pieces to get it out id put the stock system back on it and trash this ATS crap!!
