Exhaust question reply..
I would do some research on that theory before you go off spending any money because my Alero has the 3.4 in it and I have heard there is a difference in the exhaust. On my Alero I'm running OBX Racing Headers and a ecu from MP RACING,and 2/1-2" exhaust with no converter and a performance muffler off a 2006 Corvette C6 and my car runs and sounds great!
