Hey guys, I currently have a L67 with stock manifold that dumps into a 3" pipe to a 3" cat then to a Magnaflow Camaro V8 muffler, that splits to dual 2.5" out, then out to my tips. I really want to quiet it down, I know this setup is quieter than most L67 setups to begin with. There is not much room to work with here, I could possibly put 2 small resonators in the 2.5" pipes after the muffler, before the tips. Will it be worth the effort/cost? Also would wrapping the most of the exhaust with header wrap help to keep noise down even by a few decibels? Any other ideas here?

IMO, to quiet down a 3800SC you would have to custom make an around the engine exhaust system with a CAT and a standard type OEM muffler. There is little that you can do to make the short out the back mini exhaust system quiet but putting an exhaust cone in the pipe to the muffler inlet should lower the tone slightly and perhaps make it more tolerable. .
