No way your gonna add horsepower by putting a different muffler on, all you're doin is freein up the potential HP that your motor had, that the restrictive stock exhaust was holding back. And 50 is WAY high, if you replace the entire exhaust with some free flowing manderal bent pipes, that's where you start so see some gains, but probally in the neighborhood of 5-10.


Now the TRD supercharger, that's where you start to see some HP. <img src="/forums/images/graemlins/evil.gif" alt="" />
