First let me say the camaro muffler with dual exit is awesome looking...I love it. Just some information for the performance minded people out there. I'm not sure what brand muffler the camaro muffler is, but if it's a OEM replacement this is what it looks like inside. They are known to be pretty restrictive, probably not anymore restictive than our stock muffler, but maybe provide a little bit of extra sound because of dual outlet. If the inlet is 2.25 it sounds like a OEM type muffler and not an aftermarket performance muffler (they are usually 2.5) Here is a site with part numbers for that style of camaro muffler in the 2.25 OE style muffler (I believe this is it). I really like the dual setup of Rick47 it's sharp.
this could be a 1998 muffler as well they give differnt part numbers for 1996-1997 and 1998 but they both look the same maybe differnt lengths or hangar locations.
