I certainly wont argue about exhaust size, because bigger is certainly better when it comes to that aspect on a turbo car.
But a 4" exhaust would have been ample for 800 ( or more )
4" was done to match the TB, as that's what came with the plenum, so why make it 3" when it can be 4
not going to do any harm. basically.
and a 4" exhaust, from what we know/tested isn't good enough for 800bhp, it could flow 800bhp but there will be backpressure, we want zero backpressure.
Surprised no ones asked why we didn't jus use an rs500 cooler
