I've been into motorbike street racing, have figured out all of the tuning for that. Now I've moved "into" four wheels...1989 318i E30. I already have a chip, supersprint exhaust, K&N induction kit, and I'm now looking for exhaust headers that will not hit the right hand drive shaft. Of course I'm on the inevitable quest for HORSEPOWER. If anyone can help me it would be very much appreciated.
