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

I own a 2001 c2 and was thinking of making it quicker. How will a PSE exhaust work with aftermarket sport cats and headers. can this be done? i love that pse with no switch installed. porsche does not offer cats and headers from what i know. Second will a fabspeed cold air intake do any good for hp increase. Giac tuning a good idea ? i do not want any mods that will affect engine durability etc..i need regular safe mods. please let me know if this is a great way to start.

POST 2Original post

I did the Billy Boat headers & mufflers, EVO cold air induction, and the RSS plenum. I was very happy with the improvement in sound and performance. With a little ebay shopping, I did all the mods for less than $3,000. I have an extra set of 996 3.4 headers that are currently on ebay. My ebay reserve is $300. I will sell them to a fellow Rennlister for $250. (plus shipping) Good luck with the mods.

POST 3Original post

Those were my headers and I paid $899 for them....so $250 is a steal....Mark bought my car when it had a dash fire...but the engine is pristine....as are any mods that come off of it. Chuck

POST 4Original post

Thanks Chuck. I guess you could say I'm having a fire sale. It will go toward the new dash fund.
