Slalom996T

Hi

I wonder which exhaust/brand/design after the turbos that might be the closest to fulfill the following:

* Low mass...!
* The least pressuredrops, i.e. probably large pipe diameters and generous bend/s with large radius...?
* Reasonable dampening
* Not necessarily stainless steel, nor Ti

Added necessary points:

* The system need to survive reasonable hours without triggering the CEL since it will be streetdriven as well

Regarding straight pipes (L & R branch separated , i.e. non X) after the turbo's: are there any format with any dampening features available on the market?

Regarding pressuredrop: Any available evaluation of the pressurdrop/s via simulating the exhaust flow up to x k rpm?

What is the largest diameter "100 cell" cat available in a 996 exhaust system?

Do you do any research?

Speedtech !

993GT

probably Kline...

Bam!



X-pipe in Ti with anti-drone helmholtz resonators. Swap out the HFC's and throw on some straight pipe sections for better flow. I've got a similar setup in 304 SS and it's around 25-30 lbs with muffler sections rather than cat sections. 321 SS or Ti would have been much lighter but that' obviously more $$$.

So, you have a 996TT now?

Corrections, added specifications (especially concerning pressuredrop) and/or added exhaust models are welcome!

Are there any large diameter straight pipes with 100 cpsi cat's and any sort of dampening features available?

With all do respect( said like Rickey Bobby) it seems like a lot a fuss to go crush some cones I would drive the "Slalom TT" stock for a bit a and learn to drive it before you go out to beat Danny Popp. Just go drive the car and have fun. I would dare to say that the 996tt is a very capable car, seat Time is more a value at first then any mod you have talked about, just my 2 cents. From your posts you have spent over 40k easy and that would buy a lot of track or Slalom time

I'd love to help you out with any Fabspeed products for your 996T. Feel free to PM me or email me with any questions.

Anthony, thanks for your reply

It would be nice if you could supply the individual pressuredrops of the noted products of yours, assuming the're correcty noted?

Might you have a 76mm straight pipe (well, at least somewhat nicely curved) with CEL safe 100 cpsi cats with some means of a dampening feature planning to be marketed?
