where to buy apexi ws exhaust...

 

www.google.com ?? Try one of the sponsors/vendors or the wtb forum.

 

www.hopupracing.com has it for a good price, otherwise search around on Google a bit or find a local shop and get it through them. I personally like ordering through my local shop (Archer Racing...think DSM's and Vipers) because they have always given me very competitive pricing, I like supporting the locals, and its great just sitting there and BSing for a few hours.
