is yours with the magnaflow exhaust?

 

No, I previously had it straight piped. The link I posted it a compiled list of different exhaust options from other owners all on one thread. IMO, Ark sounds the best but it's like $2k. I am actually considering getting the HKS Hi-power since I am on a budget.
