Id rather do the single 3.5' for half the work and half the cost of mandrel bends... what do you guys think would be the way to go?? thanks Link to comment Share on other sites More sharing options...

(not saying the pipes dont chage anything). I think someone said it was hard to fit the 3.5 over the diff.(dont quote me)I've got a 3.5 dump and 3.5 metalcat, centre muffler removed and 3.5 spilt to std over the diff. When I first got it I couldn't stand the sound, but now its got a bit of carbon build up it sounds ok! My car is still very BOOMY when towing the Boat! but is quiet with out towing!I'll get a straight through 3.5 centre muffler then split to twin 2.5 over the diff and decent rear muffler!good luck Link to comment Share on other sites More sharing options...
