Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. 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.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hello, has anyone in the UK fitted the Gravity Performance cats and passed the MOT? 200CPI SPORTS CAT STAINLESS EXHAUST DOWNPIPE FOR PORSCHE 986 BOXSTER 2.5 2.7 3.2 ( 351973215955 ) These are on ebay, UK.

POST 2Original post

Ask to on boxa.net as UK folks frequent there.

POST 3Original post

I dont know about this cats but as they are on eBay I presume they are the same generic ones with a make up brand stamped on. I ran 100cells I bought second hand for 3 or 4 years before they eventually failed. I then bought some eBay 200 cells. First year they passed fine. Second year was a struggle and initially failed. My car did very few miles in that last year so may just have needed a good drive and Italian tune up.

POST 4Original post

21,000 km on a pair of performance 200cells CATs w/ headers. Passing inspection yearly ever since. RoW set-up.
