I was thinking catless, but bought catted as I needed to replace a bad cat and considered future resale issues.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Some weeks ago I ordered a Speedtech X-pipe catted system. John was prompt with his replies (on a Sunday in my case) and very helpful walking me through my order. After fabrication, the pipe was shipped and arrived at my door in Canada only days later. As my C4S is a daily driver, a lot of the bolts etc were extremely rusted, so had my indy do the install. Aside of taking extra time to remove the old cats, the system went in flawlessly. New O2 sensors were installed too (old ones were not coming out). The result: absolutely awesome. The system is nice and quiet at idle and low rpm and livens up 3500rpm and up. Not over the top, but you surely know it's there. Shoukd have done it years ago. Job well done by John and Speedtech team. It leaves me as an extremely happy customer. I can highly recommend them. Will try to add a sound clip when I'm home in a week.

I did a full speedtech exhaust recently. Their X-pipes are well made and fit nicely.

Ditto. I went with their catless X. Combined with XLF, it was epic

POST 5 / ORIGINAL POSTEROriginal post

I was thinking catless, but bought catted as I needed to replace a bad cat and considered future resale issues. Any sound clips?

POST 8 / ORIGINAL POSTEROriginal post

I will try a GoPro video next week.

POST 9Original post

I am considering their x-pipe with my current Fabspeed headers and mufflers. For what is pretty much just some piping, I have a hard time justifying paying twice as much for the Fabspeed. I'd like to have 100% Fabspeed system, but I'm not sure I can do it!
