Quiet cammed ls3.
I'm in the military and I'm getting ready to pcs to Germany where my car will have to pass a saftey inspection in which my exhaust can be no louder than 95 DB. My current mods are 227/238 112 cam. Tsp 1 7/8 lts with off-road connections and flowmaster super 10s for mufflers. Is there anyway I can get the car under 95db while under a load?

Germany must have really cracked down. Never had to undergo a sound measurement for the inspection.

Magnaflow axle back. Thats what Im running at its quieter than stock. Its just a lot deeper sounding. I think you can easily get away with that. Im actually looking to go louder.

I'm running a Vengeance Racing Stage 2 cam, ARH 1 7/8" headers w/ 3" X-pipe, and Magnaflow 12226 mufflers. I don't have access to a db meter but idle and cruse are not much louder than stock.It can be driven quietly with very slight throttle pressure
