I think the standard exhaust bore is 2.25" but there is a bottleneck in the original downpipe that tapers to 2". Upgrading just the downpipe frees up a lot of power - somewhere in the region of 10%.


F****** b****** thing...

it was just what I wanted to hear, I will be able to unleash this power for sure with a new downpipe. thanks to Gray for the tip on Facebook. If I didn't get this, I found another one from a company here in Germany but it's a 70mm 2.75 inch, you say it would also be fine compared to the original?
