time 4 a change of noise?
 

I'm considering putting a different exhaust on my sccoby, i have several exhaust parts laying around from other cars i have had over the years so thought as i had the equipment to make one i would have a bash. Are there any issues to the engine i need to consider that may occur from puttin non scooby related exhaust parts on it, ie ecu issues, running issues, engine going bang ! etc etc
