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.

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

POST 3Original post

I'm sorry I don't have any dyno gains with the Race Headers but these are usually 3-5 HP over the cat versions at the top end.

POST 4Original post

Besides looking easier to fabricate than the longtubes, does this catless version perform better?

POST 5Original post

The Catless header will provide more power at the top end of the RPM range since you will lose a bit of backpressure down low. This setup is ideal for a track oriented Carrera/GTS that will be over 4000 RPM.

POST 6Original post

I didn't realize this thread was in the 911 forum. I have your longtube catless headers on my Cayman and am very pleased with them. No back pressure for me...thank you. The car also runs better without a 1" hole in only one cat.
