The photos are of 996, I would like to change the complete exhaust to my 996 3.6 x 51.
Leading evidence: 'Replace complete exhaust' (no explicit attributable resolution; this is a reported action or suggestion).

HELLO I WOULD LIKE TO ADVICE, SEE THAT FOR A GOOD DRAINAGE IS CHANGING HEADERS, CAT / CATBYPASS, MUFFLER, BUT I WANT SOMETHING NEW.
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.

HELLO I WOULD LIKE TO ADVICE, SEE THAT FOR A GOOD DRAINAGE IS CHANGING HEADERS, CAT / CATBYPASS, MUFFLER, BUT I WANT SOMETHING NEW. I DO NOT WANT TO CLIMB ON THE CAT, BECAUSE I WANT Reprogram the ECU. SO WHAT DO YOU THINK OF A DISCHARGE IN PICTURES LIKE THIS? WEIGHT IS CLEAR, more straightforward:
My English is not 'the best. The photos are of 996, I would like to change the complete exhaust to my 996 3.6 x 51. I do not put the cat. These discharges in the picture what do you think? Lose 'hp low?
In most modern motors a little back pressure is good. It keeps the intake charge from following the exhaust out the combustion chamber during the overlap event of the cams and keeping midrange power losses at a minimum. That doesn't mean you can't have a less restrictive and lightweight exhaust system, which if tuned properly can add power and concentrate it in the rpm range most necessary for the cars intended purpose.
By losing the cats, some restriction and weight will will be lost as well. Some things to keep in mind designing your system, are simpler is generally better. Fewer welds, mean fewer potential areas to crack. A bend increases static pressure, just like adding length. Fewer bends are better. Make bends as large of radius as possible. There is plenty of information regarding exhaust pipe length for maximum torque. Ideally, exhaust systems can be made to help scavenge cylinders that have just fired by creating a low pressure area to help pull out the exhaust charge. Sounds fun! Let us know what you come up with.
