Thread: 4-1 Headers talk!!

damn that thing looks beeeeeaten up... but it wasnt designed by me sir. I copied mike kojima's header, used cone engineering collector (cut so the choke was exactly 2.25") and made it the length cory told me to. wished i could have transitioned it but, funds wouldnt allow, its all 1.75" runners

heres the original... made with a stick welder... no fancy shit


dyno run vs my old ssac with 2.25 secondaries and 3" mandrel bent exh

that's how i got it from u

peace

Ive yet to dyno the tri y I built we will see what it does in about a week. Im going to build a step 4-1 but im going civic half rad first to make clearance in front for more runner length.

This is getthng interesting

Let me say some thing too ..I'm about to test a triy bigtube on my 88 mm built to see if the engine likes it

Also check out the b18 rmf header its 4:1

Running the ASP race header with v-band flange. Car sounds amazing, and the power output is amazing on the car

Is it too difficult to modify to make it fit on the SR20?

Storm do you have a dyno graph of ur ve with stock header and te jmr?

Hhmmm all this makes me wanna keep my jmr header...too bad im going turbo soon
