I don't think you can get those numbers by replacing the headers alone.

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

Does anyone know if aftermarket headers for 996's truly give any hp advantage over stock? They come from the factory with headers already. Most aftermarket headers claim 12-15hp gains. Any input would be appreciated.

POST 2Original post

The 3.4L engines will see some benefit, but they should the chip reprogramed. It's an expensive proposition for relatively small gains in power.

POST 3Original post

I don't think you can get those numbers by replacing the headers alone. I do know the OEM x51 manifolds/header have the larger openinings and are standard on the "S" models. I just purchased a set from a member on this forum, however I haven't mounted they yet.

POST 4Original post

When I had my 996, I dumped close to $5K into mods...headers, mufflers, RSS plenum, PSS9 suspension, GIAC flash, EVO CAI, etc....and I'll bet I didnt' pick up 35-40 HP. I still had trouble going against Mfletch who was running a few mods in his Tip. The 3.4 L engine doesn't have much room for HP increases....especially if you just do one or two of the mods. The performance comes from all the mods working in concert....and sometimes, the mods work AGAINST you. I've seen instances of where guys post that the mod actually resulted in a reduction of HP based upon dyno info. Do your homework before you start down that mod slope....knowing what I do now, I wouldn't have done nearly as much as I did. Now the TT is a whole other matter....it sucks up mods for great gains.

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