I have Kooks long tubes into 3" cat-less H pipe, 3" over axle pipes and 3" Shelby Super Snake (JBA) axle back and I have less drone now than I did with stock manifolds and 2.5" cat-less X into Magnaflow axle backs.
The sound of my car actually mellowed out at idle and cruising speeds, when I went to long tubes and an H vs. manifolds into an X.
