The majority of the traders prices are cheap for us and group buys come up to make them even cheaper sometimes. Sometimes like with insurance you need to qoute a code that they provide in their sigs.
Thats a good exhuast and lots have it. Would also recommend a Ypipe to go with it. Manifolds are considered a waste as the improvements are minimal, especially v the costs. Most people do ypipe, de-cat/sport cats and back.
