Thread: Custom 4-1 header

Its made by local exhaust shop. Probably will be for sale soon, because owner of the car is parting out his N15. Downpipe is 60mm, its DE flange. What you think, is it worth the buy? Price asi around ~600usd.

Engine specs: RR bottom end, 11.5 CR, forged internals, worked lowport head, Tomei 280° cams, etc.

^That looks like a nice header.

yea it looks good. is that a 2.5in collector?

its 60mm = ~2.37"

How much would shipping be?

Nice built... but the collector size not is big??? maybe 2" or 2.25" for the 4-1 DE setup...?

Nice!

If he was going to make them, i would like to see larger primaries, and make the primaries a bit shorter by a few inches....But this is my opinion

with runners as long as his i think 2.5in collector will work well. but shorter runners with a 2.25 would be better for a higher rev motor.

does the seemingly incorrect pairings matter?

Looks like it has a formed collector, not a true merge.
