There’s a lot of conversation with respect to installing a header, the pipe from it to the muffler.



For those who’s wallets can not afford such an up grade...what is the best possible solution utilizing the existing stock exhaust manifolds.



Cut the flanges off the muffler side of the pipes allowing connection to a modified two into one pipe that runs to the back of the car to a new performance muffler.



Is a mid pipe required?



What is the preferred length of the two pipes before they are welded into one and what size should the single pipe back to the muffler be?



What type of performance muffler is preferred for best performance and sound/tone?

lol - these are the questions we have been asking for years - many different approaches have been tried (i've tried 8 different systems now on my car, and driven 4 others) - many claims made (most found to be very misleading and/or false)



with all due respect, i really don't see the point of having yet another thread rehashing the same stuff about exhausts - there are already 2 going here right now that have the same answers from the members to many of these questions, and a few others that did as well - the bottom line is that you have to choose your priority (performance, looks, sound), and what you like may well not be what somebody else likes



rather than get the same "i have this" or "i like that" responses, with no data to support claims, and nothing new, i think it would be best to just read the stuff already here, and go from there - there are pictures, comparison recordings, performance testimonials - yada yada

I have dug back and reviewed quite a bit...What has caught my attention is the reference to (for lack of better terms) the “dead stroke” of one of the cylinders in the firing order and its effect on the sound of the exhaust note.



I have not found any reference as to why Porsche developed a split header system, was it to decrease this effect? Moreover, has anyone cut in half the large cat and mid muffler to understand the reduction of exhaust gas speed due to the volumetric effect of these parts?



Do you or anyone else know why did Porsche choose to split the pipe again to the muffler?



Do you know of anyone who has carried the split at the exhaust manifolds with two pipes to the rear then into the muffler? It would seem if the reverberation from the dead stroke is/was effecting the sound, this would be away of mitigating it producing a different note.
