My Spirit with stock motor and full 3" exhaust (using a cat) stayed quiet. When the dump opens then it gets loud. Its fun because its only going to make noise under boost.
But its loud. Higher the RPM's get the louder it is. Messing around with bansheenut last year in my duster it was just loud when I passed him below 5000 rpms, but near the limiter it hurt his ears (him in another car). The wastegate keeps having to dump more and more exhaust pressure to maintain boost so i think its noise goes up.
The fun part of the noise is that it makes the car sound like a giant diesel truck under boost, or the supras you see in videos. I dont know how to explain jet air pump sound it creates.
I am interested to see what Cory's sounds like.
