ok here was the combination ...lsx 6 speed twin turbo 1-3/4" headers then 3 inch downpipes x-pipe 3" borlas and 3" over the axle exiting at a 45 degree angle by the quaterpanel ends
at idle it sounded like a stock ls1
regular driving the engine appeared to be louder than exhaust
full throttle fairly loud
i belive they are 16" housings
hope this helps ...by the way nice car you have

Shay are your tailpipes 2.5" or 3"? I'm leaning towards the XS mufflers, I read somewhere that they pop sometimes when you let off the gas, have you ever had this happen?
Is that the same Camaro you had the ProCharged 540 in? Or is it a new build?
Beautiful!!!
