Just got my Lethal off-road H and GEN2 OTA pipes installed yesterday, mated to GT500 axlebacks (existing). Rasp-fest! I knew it was going to pick up some sound but was hoping for just a deep rumble. On top of it not sounding good, it's just too loud. I'm probably going to toss my stock axlebacks back on. Anyone else do this? How does it sound? Someone mentioned the FRPP Touring setup for a more mellow sound vs. GT500s. I like the idea of the HP gains since I'm boosted so don't really want to ditch the off-road pipe. FWIW, I did get a revised tune file for the pipe...
