Anybody using Stainless Bros. resonators to reduce rasp? I have 1" 7/8 long tube catless H pipe and AWE touring axle backs. The rasp is seriously obnoxious!
This has not been my experience. I run the long, 23"/18" x 3" Dynomax Bullets where the stock resonators reside and have had no rasp on anything but 2 chamber Flowmasters. Needless to say, they were removed after one drive, back in early 14'.Only way to minimze the rasp is either put cats back in or go for a chambered muffler like the GT500 axle backs. I have no cats, h pipe, and resonators on stock headers. Even with borla touring it still sounds kinda raspy to me though I think it's fantastic at WOT.
