TurboXS Stealthback Exhaust Pipes Subaru WRX STI 08+
So basic mods like the Cold Air Intake and Blow off Valve did not give you the power you want. Let???s step it up a bit with the 4.5 inch bell mouth downpipe and Race-pipe or Cat-pipe version that bolts to your stock cat-back. This is the Stealthback! 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. Perfect to sneak pass the wife or the unsuspecting street competitor. 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.
Also fits on the 2005+ LGT.
