Ah, dang. I can understand that. I was listening to some exhaust clips on YouTube of some Magnaflows and Borlas and all and it reminded me of your thread from a while back.
You got the I6 or the V8? The V8s sound ridiculous with those exhausts. You ever hear of cherry bombs? Look em up, I think they're on X5s, but they're definitely on 545s and M5s.
