Using SLP LM1s right now. But i may make a switch after the hellion gets installed, will have to wait and see if i like the sound. Tho im already on my 3rd catback.
I just had the Magnapacks put in my car along with a full 3" cat back. Sounds pretty timid at idle but when you go WOT it sounds like a turbo Cobra should.

do you have any vids?
Rolling with borla stingers, they sound sick.
