What range of sound readings are you guys getting with 2.5 dia pipe and no
muffler? . I was concerned with high readings and curently have a 2.5 pipe
and muffler installed in the stock location but my sound is way down 83.
MY car is a 6. Is any one running a short pipe exiting forward of the rear
wheel. those sound #'s would be help full Also the can Kas has mentioned
will it help lower the sound ? thanks rob
