decats on diesels pass. they are not tested. It's smoke only.
Its the back box which really dictates the sound. With it all removed it's obviously louder, but I didn't find it bad at all on motorways etc. It only became really loud on full chat.
After following the wtcc and btcc for years I noticed that the diesel leons were unbelievably quiet under all conditions(usually loads of throttle) so noisy may not the the way to best power? surely competition building guys would know best, could there be any replica kits out there?
they have to abide by all sorts of regulations, including noise limits?
Egr was cleaned 10k ago and since then was turned down to 1% function.
I have fitted an oil catch can too.
It's just something that's bugging me for a car @74k miles.
Egr was sticking after if was cleaned - open one minute and then closed and the exhuast note would change.

U say u have a custom catch tank. The Reason am asking is because the pd engine if that's what u have has a lot of crankcase oil pressure and require a lot of breathing.
And if its not breathing enough it can cause it too over fuel so I'd defo start by cheaking out ur engine breather system.
if it was sticking, change it for a allard power pipe or something like it maybe?!
So would diesels require to be nearly silent whilst petrol versions very loud?
