OBX High performance racing headers are made out of pure SUS-304 stainless steel. Dyno tested at low end and top speed to increase 7~10 horsepower. Precision mandrel-bend to enhance exhaust gas flow. OBX Headers will fit OEM down pipe or OBX Cat Back Systems without modification. These 2 piece type headers are easy to install. Value-added bolt-on headers for any racing sport performance enthusiast. CARB exempt.
-Dyno Tested and Proven
-Direct bolt-on without modification
-T-304 Stainless Steel mandrel bend for ultra fast flow.
-CNC Machine flanges with TIG and MIG welded construction
-02 Sensor position
-Hardware included
-Lifetime warranty from manufacturer defects.

Over all impressions with this 4-2-1 2 piece header on a 92 hatch with D16z6:
1. Fitment SUCKS, the angle of the header when connecting to the cat converter is off to the passenger`s side almost 2"s. For this to properly bolt in I had to move the converter a little to get it to bolt up.
2. Welds looked very lousy. I am by no means a pro welder, but I do recognize quality...nothing to recognize here. I`m just wondering how long it will last before it starts leaking. Speaking of leaking, the gaskets they include appear to be way too soft and fragile. I doubt they would last very long and I do expect them to leak over time.
3. Engine doesn`t sound that great with this header, as for performance I really doubt it adds any horsepower. I do believe it does flow a litte better than the stock D15b7 header I was using on the D16z6. No dyno sheets to prove it and I`ve yet to see this header dyno`d (although I have not done a lot of research).
You`re probably wondering why the hell I`d use this header? One of my friends gave it to me, so it was free. I really wouldn`t recommend actually spending money on OBX stuff.
After I get my clutch broken in I`ll take it to a dyno for some tuning (probably by the end of Feb).
