holy crap new m3

sorry I couldn't find a better pic, but just from eyeballing it, the twist makes them pretty darn close. Either way, sure beats the log style manifolds they used on a lot of other BMWs.

Yeah, the M42 manifold beats the shit out of these:

and it looks a lot nicer than that spider web of tubing, if you ask me

I guess if you have a big carb'ed v8 with 50hp/L, looks are more important than efficiency.

That said, you're on crack if a rusty looking cast-iron log manifold looks better than a proper set of coated long tubes, like on the M3 V8.

you know 50hp/L isnt much, right?

I'm not talking about the type rex just posted..I'm talking about like 3 1/2" log that runs across in front of the exhaust ports in the head, and then the tubes come out of that - so it's all collected right at the cylinder head

Thats the whole point, v8 fanboi

Well, anyway, the whole point of a system like that is to increase scavenging. I did a lot of looking into all that when i did my exhaust system - I couldnt afford equal length headers, but I do have shorty style headers with 3" collectors going into 2 1/2" pipes with an X-pipe

I dont think that qualifies me as a fanboy...a fanboy would have kept the stock system wtih like, some sweet cherry bombs, yo...or flowmasters!

Equal length headers ftw! Too bad my car doesn't sound like a boxer anymore =(

Looks like there are piston rings... although only two of them. That is one hell of a short piston though. The rods look like they're "broken" too - i forget the correct technical term for it, but it gives a better fit on assembly than a flat rod cap - ford did this on some of their engines i believe.

*yawn* two-ring pistons and cracked con-rods are old news for bikes. Looks like they stole some tech from the K1200x motor (which was stolen from their F1 motors) for this thing.
