3" Stainless Exhaust
Nice System, Great finish and it fit well with only slight modifications. Sounds nice and really woke the Turbo V6 up!

3 inch polished stainless exhaust
This is a beautiful exhaust that fit perfectly. I bought the band clamps and 3” test pipe with the exhaust. I purchased on Monday it arrived on Friday I live in Florida. I have owned my GN for 29 years and would recommend this product and GN1 Performance to anyone.
