If the downpipe is long enough to pass the front wheels and is directed away from the motor horizontally we are going to allow it. What we are trying to avoid is just an open dump straight out of the manifold or turbo (depending on yoursetup).Originally Posted by 93H22ACX
Hope that helps clear it up. If you have an open DP and it runs away from the engine and runs horizontally you will be fine. Wastegate dumps are exempted.
