what routing are you using????down dumps before axle are noisy----out before rear wheel area not as bad but out the rear is best----


I use components for 2000-2004 mustang clear coil overs and lay below rear frame rails beside fuel tank


Also look at the side pipe set up on the 32 in my gallery


Choice of components for me is Magna flow stainless---you can get about whatever pipe diameter you want


however will those lower rear end bars toward the middle be a problem?????
