More details on the exhaust. I see a single pipe leading to the rear can.

hmmm bought it with that. got 50/50 manifold, followed by hi flow cat, then magnaflow resonator then (not sure on brand) muffler. its a single 2.5" system.

Wow I opened this and was shocked at how clean this thing is and how much time, energy, blood you put in to this car. Looks gorgeous. Just read the build thread. Thumbs up!

can i get some advice on exhaust / cat setup please:

i got a stock 2.3l with dogleg box and 3.73 diff.

its got 50/50 manifold going into a high flow cat and single 2.5" pipe.

i have read that 50/50 manifold came on catless M3's so am wondering if its worth taking the cat out on mine? is there any gains to be had or hardly noticible.

also i have been told that i should have a larger diameter pipe going from 50/50 to the cat (3") and then after the cat, keep it 2.5".

thoughts?

thanks guys
