I will also have a turbo on each bank, which should help quiet it down with a turbo muffler as well. I think I will do the cut outs with front side exiting, and run exhaust out the back for peace of mind. This car had exhaust out the back with turn downs below the bumper. It just had glass packs and 2 1/4" exhaust with maybe 9:1 comp. So nothing super wild. It didn't sound too bad for what it was after the cam and intake swap.
