Yup, single 62 mm built by AMS. Hands down some of the best sounding exhausts. I might get an exhaust made by them for the Z. The power is so raw from those things since their welding is so good. Might be able to get rid of my QTP dump valve with a nice exhaust. I'm afraid to ask for the price of custom welding me a cat-back though. I see about $1000, where I can do it for about $100 with same results lol. I'd like to step up to a 4" exhaust, but that may be difficult with my car height.
Hopefully I can have some fun in the Z with a few cars in a couple weeks before the season is over. I want to make people cry that they got beat by an 80's car.
