I was wondering if i decide to get the test pipes will i get more HP. Iv heard you can get like 10 from just diching the cats. What about the High Flow Cats will it make my exhaust any louder or give me any more power than the stocks.
 
There is zero gain in power for NA cars, you're supercharged, so it might be a different situation with your car. As far as sound is concerned... many people with the stock exhaust report no increase in sound with test pipes, aftermarket exhausts are a different story - I have taitec test pipes with a Zee's exhaust, and the sound is probably around 30% louder with the straight pipes.

IMO do it for the noise if you want, but paying for high flowcats is not worth it imo unless yours are blown out anyway. I would spend it on other areas of performance. catless smells, but on my SC car it makes me smile when I hear it. I live down the street from you if you want to come over or meet up to hear it. I may dyno this week to see the gains. I was only at 336 with them in :(

Personal experience. With Test Pipes, the power increase will be minimal on NA, BUT, the power/torque curve will change. Power on my set up with test pipes comes about 200 RPM later than with cats.

My 2 cents
