Help with Exhaust
I have a 97 Z/28, I replaced the stock muffler with a flowmaster when it burned out i went with the Flowmaster cat back system and believe it or not it slowed the car down 4 Tenths in the 1/8 mile. Could someone tell me the stock size Dia of the pipe that runs from the cat to the muffler and the stock size Dia of the tailpipes i am thinking that the pipes that came with the Cat Back System are to large in Dia this is a Stock Z/28. And the MPH didnt change it was the 60ft time that changed. Thanks
