Suggestion
Here�s my question: how much weight could be removed in the car, such as changing the seats or using a lightweight battery, to equal to 10HP gain from an exhaust change?
Leading evidence: 'Replace seats or' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace seats or' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Suggestion
If one was already going to replace their exhaust by dropping a couple thousand dollars, then why not also get one that has some HP gain - I get that.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

What everyone looking at this needs to consider is everything except the peak figures... I can look at those curves and see a lot more than you guys can, I could tell more if I was in the car doing the test myself... The feedback through the car/ engine is more important to me than the dyno plots, or "data".
Yeah, I also don�t like super loud exhaust systems.

If one was already going to replace their exhaust by dropping a couple thousand dollars, then why not also get one that has some HP gain - I get that. But if it�s HP we are after or light weight, the battery and spare tire is where I�d start. Then seats.
I didn't word my response well. What I meant was straight pipes gave 14 peak and a gain across the board of about that. I would think that straight pipes are the best you can do to free up an exhaust. So any exhaust system you add will not top the 14 number. So with a stock engine, Porsche pretty much designed the exhaust to work very well and adhere to noise limitations.
What they didn't show was the direct AFR values in these tests.. Corrections made will net different gains.
This series of Bosch ECU will further enrich the AFR values with a more free flowing exhaust, and do so at a rate that will cripple net power.
I am currently experiencing that right now.. Like 5 minutes ago, as I continue development work.
I�m keeping my stock seats for now.
I�d like to swap them out someday.
I have Planted floor mounts and side mounts, but no racing seats yet.
Since my car will return to daily driver status some day, I need very comfortable seats for my daily commute.
Some racing seats I�ve considered state they�re not for waists above 36�.
That wouldn�t work for me or my occasional passengers.
I need something that will fit 38�.
I have considered Recaro Sportster seats, but I want to try them out first.
