Just wondering what sort of power gains you saw when using the 4-2-1 GYMKHANA header.

 

I've got one, actually Dave at SMS has it for repair.....

It's a nice peice and has very different characteristics than the 4-1 version. Very noticeable low-end and mid-range gains. I never had it one the dyno, but the difference was noticeable in the seat of the pants. Top end trails off pretty quick around 7600rpm.

I really like the header and I'm lookng forward to getting it back with some SMS mods

 

Here's a plot from Igg's car when we did a little dyno build.

Number 3 is baseline of a bone stock itr, #4 is with a Comptech Icebox installed, then the next run shows it with the Mugen 4-2-1 header, Carsound 54006 cat, Mugen exhaust, and a VAFC with slight changes.

Not the best example, but it shows you what you get, and where you get it.
