Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Ok here goes....I am thinking of doing a mod on some stock C4S exhaust boxes. Could do with some information if anyone can help. I was thinking of welding a crosover pipe from the inlet to outlet pipework (know an ace welder) and was wondering what diameter to use for the crossover, Do the pse exhausts do something similiar (with a valve in this part) and if so, what is the outside diameter of the pipe? Lastly, has anyone here done this? please get in touch if you have! cheers ,David :mrgreen:
