      im changing mine up to use the entire m20 system. I've heard the b35 downpipes slip over the m20 exhaust after some cutting to fit. Correct me if I'm wrong.

          Yes the B35 pipes slide right over the M20 exhaust right before the cat, I have done this before. They will require welding though since it's a little loose.

            On my B34 I ran the M30 Downpipes to single 2.5 magnaflow resonator to a magnaflow Xl muffler. Sounds pretty good, does have a bit of drone, but was uber cheap.
