My exhaust is 3".
You know what is weird..... They are louder from 2500-4000 Rpm with a load on the engine. They quite down a lot in the higher RPM's. When I do a hard NOS blast it really quiets down. The pitch really changes. Also there is no drone in the car at all with the mufflers in the back. Just something I have noticed.
Sweet work on your ride. You are a trooper without a doubt! :cheers:
