  1. Stage 1 vs 2 - And Exhaust Question

    Engine Modifications

But wow the difference in cost is like $1300, for a gain of 14 ft lbs and 7 whp, worth it? I personally do not like the sound of the Perrin exhaust so probably doesn't...

    New Member Introductions
    I just bought a WRX about 6 months ago and am looking to put an exhaust system on it. My friend had a Perrin exhaust on it (dual tip) and it sounded great. A little rumble/purr sounding. Is Perrin a good exhaust? If not, what kind and how much am I looking on spending. Thanks
