Hi,

i am new to this forum. usually 993tt forum.

want to buy an exhaust for my brothers 951. Has a lot of cup parts and was modified by porsche employee with a lot of parts from research departement. Think it has been way over 300hp if i compare it to my tt. Engine blew up a year ago. Now it is more like < 300 hp but still fast.

I had a look at the sfr homepage and did a search here.

dont understand all terms (bad englisch).

Want a 3" pipe from turbo hot side, if that makes sense.

Possibility to plug a cat in for TÜV and AU, that is german emission test every 2 yrs would be nice but not a must.

My brother had some no cat test pipe with stock muffler in all 2.5" i think.
that was not to loud.

Any recommendation list? Any audio files? Please only turbos. Please keep it simple so that i can understand it.
Perhaps some parts from germany?

TIA,

Stefan

SFR 3" cat-back would work.
3" test pipe will allow you to slide in their high-flow cat.

Sorry, I haven't found a Turbo sound clip yet, but the turbo is much quieter.

Thanks Ryan,

any experience with 951 and 3" cat-back?

Any power improvement or better boost?

I personally have no experience, but try posting that on the Turbo board as a lot of them run that system or PM "Turbo Tim" - he works for Speed Force and drives a nice 951 with one and can recommend stuff for you.
