My Exhaust Combination

Hi,

i got the RE diablo catbacks for my z4m and fabspeed headers also

i am thinking of the following combinations to complete my exhaust system:

A) rogue engineering x-pipe

B) supersprint sec 2 catless pipes

C) supersprint sec 2 catless pipes + rogue engineering x-pipe

which are the pros and cons of each combination?

Agreed. I say do none of the above and save your money for a Gruppe M intake or supercharger.

I agree with the above.

(FWIW, the CATs section is known as section 1)

Thanks for replaying..

So no and no for b) and c) bcoz of rasp

How about a) xpipe only? Rasping also?

Power gains?

so with my car i sent from RE cans to RE cans and RE x pipe first and the added difference was a tiny bit of rasp when the car was cold. it probably added to the note of the car a bit also. Now with addition of Euro headers, the car has plenty of rasp. I also added a Grouppe intake after everything else and the car sounds completely different than when I had RE alone.

If I were in your shoes, I would either go with Grouppe alone or plus a tune and skip on any more exhaust changes
