I need a new muffler for my 1997 Pontiac Firebird V6. It has a dual exhaust. Every muffler I have looked at online has a different intake and outtake size. Some have 2" intake and 2.25" outtake. Some have 2" for both intake and outtake. Some have 2.5" intake and 2.25" outtake. I am having someone put the muffler on and don't want to buy the wrong size. Please Help!!
What is the standard intake and outtake size for the muffler on a '97 Pontiac Firebird?
