I have checked for torque on headed flange bolts to make sure they are not leaking either, so, eliminated that.
Leading evidence: 'Check torque' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'same keyboard warriors' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check torque' (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.

I am also guessing some of you cannot even turn a wrench on your own car, probably the same keyboard warriors.

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.

I know there is probably a thread for this, but, did a quick search with nothing concrete...
I have lost some low-end throttle response and what feels like HP, somewhat expected. It happens more once the pipes heat up.
But is there a solution for this? Just curious. I feel like rolling the clutch so long every time I leave a stoplight will get old.
Yeah, makes sense. I have considered that. COBB or someone similar? I am in Denver, so local would be nice. I may upgrade to that GT3 throttle body, not a bad idea either and not one I thought of. Thanks for that. I have checked for torque on headed flange bolts to make sure they are not leaking either, so, eliminated that.
Well, when I did it on my 964 there was also an incredible stink. So there's that too... I finally figured out why I couldn't get chicks. I put it back on and then I was a rockstar. Haha.
I would consider a sport cat but won't be going stink butt anymore.
There is no doubt that without the back pressure you have lost torque. My car has a fister exhaust and I can notice a slight change in low in torque compared to my friend's 996.1 with stock exhaust. Your setup is just much more severe.
Most cars require the pressure feedback at the cat to operate correctly. If you take it out, you need to tune it, or time it differently (I think delaying the exhaust cam a few degrees) which is not easily done on the Porsche.
Man, some of you keyboard warriors... lol Always makes me laugh, so thanks for that. This is a track car build, that gets driven on the street some.
Furthermore, who cares about the money? I also wanted a tune anyway, was always on the build list. I am also guessing some of you cannot even turn a wrench on your own car, probably the same keyboard warriors.
Regardless, to those of you who actually commented with intent to help, thank you.
I did it for sound. It sounds amazing. And zero drone.
Weight. Its definitely lighter.
And power. It feels noticeably more powerful. With the tune, the throttle pedal has way more feel. I felt the change immediately. Mid corner throttle inputs are far better now. Its not a massive power jump, but it definitely pulls better than before.
Plus, the car is a toy. It just added to the enjoyment.
Completely agree on the pull. It definitely has better apex and exit pull. I like it. On the street, sound is good without drone and quiet when I want it. I definitely was looking to a tune soon regardless of pipe. I already bought a GT3 throttle body and I will get that tune shortly.
I imagine in a track setting, with a tune, you may see some additional oomph at high RPM's as well. I just never saw the point of cat elimination for the street. At least go with 200 cell cats or something.
To be fair, your question sounded 180 of what you just stated, it sounded like casual driver noticed performance loss ,,, how to fix?
Its really how can I keep my low end power up on my track toy..
Lot of options so the answers will be all over..
