I have had slp loud mouth axle back on my 2006 gt for a while now and liked them. Now that I put a procharger on my car though I don't like the sound. At high rps it gets real raspy and I hate it. So I am going to sell them and get a new axle back but I'm looking for opinions. What are you guys running and how do you like them? I like an aggressive exhaust sound and I only drive it on nice weekends so if there is a little drone it's ok.
