Hey all, I'm refreshing the exhaust system on the Box, and while I have apart (new Che muffler), I want to also replace the Che cat bypass pipes I installed like 15 years ago.

Also they say they will connect directly to the stock C pipe pieces, but in my current ones I have this little extra 8” or so connector pipe between the test pipes

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hey all, I'm refreshing the exhaust system on the Box, and while I have apart (new Che muffler), I want to also replace the Che cat bypass pipes I installed like 15 years ago. I noticed one of them, the angle isn't quite right coming off the header, so it's rubbing on this "tab" thing on the transmission.. not seeing an easy enough way to correct that, and don't feel like modifying the tab thing on the transmission. I recall these being fairly cheap (like $200 or so) when I got them originally. I'm scouring ebay, but can't find a set all of a sudden. Does anyone know of a current source for these? Wouldn't even mind getting the side "C" pieces as well if there's a set of those available cheap as well. (2000 2.7L base - so no linking to $5k fabspeed packages lol)

POST 2 / ORIGINAL POSTEROriginal post

I still have my stock headers and first set of cats. Are these the same thing that I have on now? (cat bypass pipes as I knew them to be called) https://www.spelabautoparts.com/products/downpipe-exhaust-for-2000-2004-porsche-boxster-986-2-7l-3-2l-spelab?variant=44250415726843 (no affiliation)

POST 3Original post

I have the circuitwerks ones. Google for their website

POST 4 / ORIGINAL POSTEROriginal post

Cool! Thanks for the recommendation! I ordered their set of “test pipes” and some new “C” connectors. Question: these are the ones I ordered ( https://circuitwerksusa.com/products/00-04-porsche-boxster-986-2-7-3-2-straight-test-pipes?pr_prod_strat=e5_desc&pr_rec_id=e43705460&pr_rec_pid=7204250124485&pr_ref_pid=7204252090565&pr_seq=uniform ) My current ones don’t have the 02 sensor bungs or the brackets on the side. What do those mount to?it says these will connect to my stock headers. Also they say they will connect directly to the stock C pipe pieces, but in my current ones I have this little extra 8” or so connector pipe between the test pipes And the C pieces. Will this setup eliminate those extra pieces?

POST 5Original post

That's what I used. I replaced my secondary cats with them. They connected to my stock exhaust manifolds and exhaust without any modifications.
