/\/\ Exactly this.  More and more people are running side exit exhausts now.  Also as said the mapping makes a difference - I had a very smokey map and got black flagged from Donington because they thought I was broken

I got black flagged at Blyton for being too smokey - looking at going for bigger injectors to try and reduce the smoke.
