You mean, you don't like the sound and hope that it will change ? In this case...no...

Since it's used, chances are that it's already broken in

Don't rev the car over 2K to 2.5K for the first 5000 miles on a newly acquired exhaust!
The car's DME has to get used to the freer flow exhaust and make adjustments to timing and fuel accordingly. Boost will go up 2-3 psi too! Since you bought the exhaust used, there is no break in period. HOWEVER, if you do by a new exhaust, you should also not rev it for at least 5 years. You don't want to overheat the glass pack in the muffler section. If you do, your exhaust will DRONE! Other than that, enjoy your new exhaust system. |

Uh... no. Just no. Seriously.
How bad is it that I can't tell if someone is posting this thread as a serious question or not on this forum?

The tone changes My PE exhaust sounded much better after a few hundred miles than when I first drive off Really seemed to settle after 1k maybe 2k His is already most likely broken in. Since it was used Not sure what u meant by the whole serious comment Last edited by Shahdog; 07-23-2012 at 01:38 AM.. |
