I have a 2000 SS camaro with factory exhaust. I want to replace the muffler only and am having trouble finding the factory size of the pipping. Can anyone tell me if the inlet diameter is 3", 2 1/2" ect. and the outlett diameter as well? My car is not here for me to measure so I have been searching everywhere.

thanks!

Depends on which factory catback you have. If your muffler is stainless with several rivets visible on the case its the slp dual dual catback and yes it is 3" in, 2 1/2" outlets. If its the regular factory catback, the muffler just looks like a typical cheap muffler with nothing on the case, then i believe its 2 1/2" inlet, 2 1/4" outlets...not real sure on the regular stock sizing though, but I know for a fact the dual dual catback is what I wrote above.
