How LOUD are you. A poll!

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.

According to the age of my car the engineers report states that it had to comply to 98db but I think they are a bit more than that.
Here is a rough sketch of the internals of my side pipes.

I think the pipes must have had a lot of scourers stuffed in them for rego.
Cheers,
