Got the Decat from: R.A.I. Motorsport B7A4 2.0T Test Pipe
It's the only 4" to 3" pipe on the market as far as I know.
Initially it was very loud but over a period of time the system has coked up and the noise is much more refined.

If u do a decat with straight thru exhaust it will be loud!
I've not done it on my A4 but done it before on a previous car and it was ridiculous and it lasted a week before I took it off.
