Hey Ark,
Just wanted to say thanks for the great quality of work that you do. Got my Grip Exhaust burnt tip in today and had it installed. Sounds and looks amazing. The only thing that I had a problem with was that you guys didn't have enough gaskets.... I had a problem with this when I bought a Grip Exhaust for my previous G37x sedan. Overall good job and thanks again on the great exhaust and great customer service!
