This exhaust starts off with the TurboXS 4.5 inch bell mouth downpipe and cat delete / race pipe that bolts to your stock cat-back. This is the Stealthback with 90% of the gains and 10 % of the sound up until 300 whp. This is perfect for anyone who wants a nice daily driver without additional noise. Just bolting on the Stealthback you are a looking at a 25 ft-lbs. and 25 hp increase at the wheels. If you couple this with tuning you are easily going to pick up 50-60 ft-lbs and 30-40 whp.
