Pipe Size and Muffler Application
What's up everyone...I have a 1991 Camaro RS with the 3.1 L. I'm looking to change out my muffler, but first I need to know what the standard inlet pipe size is for my particular engine. I know for sure the outlet pipes are 2.5" and the inlet pipe is a bit smaller. If anyone has some info for me, I'd appreciate it. Thanks.
