FS: PTUNING 4-1 Equal Length Header
 

I recently parted out my FR-S and am selling my lightly used PTUNING header, I ran this with the PTUNING turbo kit and had excellent results. Header is in great shape and has some nice color to it.

- Custom spec 1/2" thick CNC T304 SS head flanges with back cut gasket face for better exhaust port gasket sealing.
- Custom spec 1/2" thick CNC T304 SS 2-bolt overpipe inlet flange.
- T304 SS v-band near merge collector for possible future upgrades to a full v-band header back exhaust system.
- Runner lengths designed around the offset cylinder 1 and 4 exhaust ports on the FA20 cylinder head.
- All 4 runners lengths are within 1.5% of each other from the back side of the exhaust valves to the merge collector.
- Rotational firing order into the 4-1 merge collector. Only one of it's kind for the FA20.
- Double-Slip 4-1 merge collector with custom spring tabs to allow for proper heat expansion without the need for flex bellows. Only one of it's kind for the FA20.
- Minimal exhaust runner up sweep at the front of the engine ensures that radiant heat is kept to a minimum. This also makes this header SC friendly.
- Low profile design allows the factory metal under tray to bolt back into place without any modifications or spacers.
- Each mandrel bent exhaust runner is constructed using the fewest number of sections possible. This ensures perfect exhaust flow as well as eliminating the need for extra weld joints.
