Your product bolted up to my 370z perfectly. And the sound is great. I would highly recommend to anyone. Thanks.

Nicole Campbell (Pittsburgh, PA, US)
Great sound.

For whatever reason they didn't just bolt on. Had to cut and weld to the mid pipes. No biggie. The sound is great though. Happy with the purchase.
