Bellmouth Downpipe
Is there an actual benefit of one of these over the standard ?
Just appears to be such a minor change over the standard that I can't see the benefit/s if there is one or any ?
Cheers

Bellmouth downpipe is quite a bit different to std, much more opportunity for the wastegate to flow, here is a comparison pic I found on the net. On the std downpipe the wastegate flows against the flat plate.

It came on the car mate and its been mapped before I bought it. Previous cars didnt feel as urgent and had been mapped but not with an open mouth. I like changing exhausts but wouldn't change the downpipe style.
