now you need to do a catback upgrade such as 2.25 inch piping with a high flow muffler such as flowmaster, borla etc. You wont really get a good reading of new power because the exhaust is not free flowing to the cat, and then stuffed through 1 3/4 +/- stock piping, so power is not helped out too much. Thats what i plan on doing to mine come spring.
