HMMWV headers

[dam88]

Quick Question:

I see what looks like better flowing exhaust manifolds on the engines(ex-HMMWV) at GL. I'm guessing these are more free flowing than the exhaust logs on my M1028.

Has anybody swapped these into a CUCV? Anybody got any dyno info on these vs. the stock logs?

Thanks,

DAM

They do not fit at all. the passenger side one will try to exit right where the framerail is. They are not a good header design, and fyi diesels dont really benefit from headers. You'd be best off to just run a 3" dual exhaust or put a turbo on the truck.

That's true. The only way you can benefit from a diesel is to turbo it or run the 3" dual exhaust.

Hey CC, can we put this in the FAQ somewhere? Seems like this gets asked once a month or so.

I had a set of those. Worst quality headers I've ever seen. Ugly welds and shocking to look inside them. Looks like the individual pipes were cut with a hacksaw and jammed into the collector (? Main body?). Really rough work.

As mentioned they only work on Hummers.

Yes...I think so too...but they cost only 78 €...

....We can`t mess these Headers like H P Parts from a Supra or Corvette ....
