Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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

Dropped my C4 off for a service yesterday and as I suspected the exhaust has indeed started to blow slightly. So my question is 'what exhaust systems to people recommend?' Also, is it possible that some exhaust systems will increase performance, and if so by how much? Excuse my ignorance but what's the difference between a sports exhaust and the standard one?

POST 2Original post

A lot of people here like Top Gear exhausts, do a search for more into. Sports exhaust, a lot noisier, some like them, some don't

POST 3Original post

You need to be more specific on it's blowing. It is the back boxes, manifolds or cats? Replacing the full system can be very expensive and you might only need new back boxes.

This is a source reference. Confirm exact model applicability in the original material.
