Yeh I think I will go with the ashley item its £200 on burton power which comes fully assembled, they also do an ashley single silencer exhaust for the mk4 aswell which is about £180 which shuld sound pretty meaty.

If and only if I were to go with carbs at some point would I have to run it on standalone management or are any of the zetec ecu's capable of doing the job? If so megasquirt seems to get a good write up on here so I may go with that
