For a factory peice, its pretty good, but its really more of a tubular manifold. There is plenty you could to improve on it.

I'd like to see a list of things you could do to improve the M42, lol, tubular manifold as you call it. The runners are all but equal-length and split into proper exhaust-pulse separation. But i seriously would like to hear your thoughts.

equal length doesn't matter

for one, they have butt-collectors. also, look into a 4-2-1 merged header, or even stepped headers. compared to a 6-cylinder, proper merging of the pulses is far more important on a 4 cylinder. the stock manifold basically gives the gasses a path to exit the head, but that's about as far as they took it.

I'm sorry I ever gave you credit for being a knowledgeable source.
Also, sorry for the thread-jack OP, good luck with your headers ;)

Okay. Just keep buying what people sell you. you're right - equal length matters more than anything! better measure that down to .0001".

Since you're in L.A. area, get in touch with Robert from e30motorwerks as there's a custom exhaust shop right next to his business.

Rob and I spoke about doing something simular a few years ago., it's still rattleing my brain.

the primaries look a little short for 99.99% of the M20 out there
