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.

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

Hi Folks, looking at a bit more engine note from my 996. I have Fabspeed mufflers but i like the extra note of high flow 200 cell Cats. My options are: 1) Buy high flow cats - expensive. 2) Modify the std cats and replace the internals with high flow 200 or even 100 cell internals. 3) Modify the std cats and machine holes in the 400 cell material to improve flow. What are peoples experiences with either of these options?

POST 2Original post

I bought the high flow cat option with the IPE exhaust system. From what you have above, the best 2 options woudl be to either buy the replacement cats to match your system or two cats to replace the standard cats and have then welded into the stock system.

POST 3Original post

Have cargraphic 200Cel xpipe would highly recommend them.

Much nicer note??

POST 5Original post

I'd say definitely but exhaust sound is subjective! Also have cargraphic mufflers & headers. Also we have had experience with top gear xpipe on a friend's 996 which just be weary can start to rattle due to thermal expansion after awhile. We are a cargraphic distributor so feel free to drop me a PM and we can get you a price if you'd like.

Awesome! Thankyou. When im ready to go will do. I've got Fabspeed mufflers, but stock headers, and stock cats. Cargraphic wheels though too.

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