I run a 2 1/2 inch perforated tube wrapped in fiberglass in my 4 inch side pipes. This was fine when short shifting arround town and cruising at low revs on the freeway.

The new engine is a different story, the same pipes are now extremely loud, I too need to find a way to quite them down.

The noise tests are a joke, i had a simple under the car exhaust that was quite in the first place, but not quite enough. I stuffed a few stainless scourers up the pipe and that go me thru. the car was just running.
