I talked with my dealer and he said could do it for $1188. I thought it was high, but it would be the dealer installing. However, once I dropped the car and exhaust off they called and said "they couldn't install, because it needs to be welded". I was like, Dang!!! So I went to a couple of muffler shops and people came out of the woodwork to look at the car, but wouldn't touch it. Finally I found the "biggest" shop in corpus and he could do it for $449. But I was worried when I was explained why I wanted to change out exhausts, he said "it shouldn't make a difference". So after a tense/nerve racking/gut wrenching afternoon, he called and was finished. The 3rd pipe over is a little high, that's probably my only grip, but when I started it up. I thought "oh yeah, this is it". It is awesome!!!. I don't have the option to turn on/off, but why would ever need too?
