hvcone, were your original pipes black at the output? I have what I believe is significant sooting of the pipes. I am reluctant to get a tune done until I get the headers bought and installed. The Borla instructions recommend cutting the pipe after the muffler rear mounting brackets just before the rear spring, I may do that but I have to remove the springs anyway to put the GF 2/2.75 lowering kit on so am up in the air about the process.
