Sean, took the R36 down to evolve technik today and had a lengthy discussion with Neil and Peter. They put the car up took all the photograpphs of the exhaust that they needed and were going to have a talk to miltek about altering the exhaust system to provide a better note and see if there was anyroom for power increase. As far as the ecu upgrade, they said they can do it now, but im looking at doing the two togather. ive also asked them to furthur investigate the possibillity of a turbo as HPA motorsport have already introduced in germany. They have contact in Germany and will do futher investigations for R36 upgrades.

there going to contact me back with information regarding the exhaust, and ill keep you informed.

Cheers
Hope this helps
