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.

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

POST 1 / ORIGINAL POSTEROriginal post

Looking at installing the Fabspeed cat bypass on my 2001 996. Is this a DIY? What is involved? I assume PB Blaster will be my friend. Also, I know to protect themselves Fabspeed says the cat bypass systems are only for off road or track. Realistically, I just want a beefier sound and don't do the track. Are these okay for a street car?

POST 2Original post

Yes, lots of pb blaster It’s fairly straightforward, unbolt the cat flange from the header, and the slip connection from the crossover pipe and bolt in the bypass pipe It will be louder, and likely will set off a check engine light Do you have emission control where you are? If so, you will have to reinstall the cats, then do the drive cycle to reset the cat monitors prior to smog check

POST 3Original post

I tried a Cat Delete from Vertex. It is not an X pipe design like the Fabspeed one. With Fabspeed mufflers it was just a bit over the top on the amount of noise on the throttle. I replaced the set with a Fabspeed 200 cell X pipe set and have been really happy with the result. I had to cold chisel my bolts off. ARP bolts work for replacement. I would recommend new connector clamps if yours have any corrosion or grit in them. My old ones just would not snug down good enough the seal the gas flow.

GSpreeman Feel free to give me a call to discuss the system.
