Im running twin 50mm pipes (scorpion M3) as this is what an M30 is suposed to run best with but when i was using twin 46mm pipes (325i system) it seemed to have more low down torque but started to run out of breath at around 5k.

twin 50mm M3 scorpion parp pipes here too. i've not had it with any other system on but it's the same bore as the original E32 735i system so can't be bad

I'm using 3'' with a bullet muffler in the center, and big magnaflow at the rear.
Ugly as hell, but it's been leak tested.
