None of these bolt on exhausts do crap for HP in the real world. The manufacturers may post some BS numbers of a contrived test on their own dyno for 5hp (PEAK!) gain. These tests, no doubt, are totally biased with a worst-run stock compared to a best-run modded. But the gains they claim are within the "noise" of just running your car a few times on a dyno. When you see actual results of real cars in the real world, the gains are negligible, if any. Comptech is the only honest company since they don't claim bogus gains.
