Looking for a decent cheap header, it will be a custom exhaust after the header so just looking for a little torque increase if any. Like the title states does anyone run this obx header and have any comments or concerns with it?
Other options are also fine

Theres tons of threads on this. Many people have a OBX/Raceland/Topspeed header.

Which would be the best route? I looked in the exhaust subforum and didnt see anything on obx

I'd get the Raceland header, I have it and love it. No problems so far and I've had it for a few thousand miles.
Mine's the 1.6, but it's not much different.

Thank I'd love to have opinions on what's the best

Some have said the Raceland can contact the bell housing, nothing a little ingenuity wouldn't fix I'd say.
I bought a 1.8 one but never installed; the welds were good.

For something more expencive next time...

 

[MeYahTah1]

Anyone with opinions on the 1.8?

 

[2ndGearRubber]

I have a 1.8 (an NB though). I bought an OBX header, and a Racing Beat header is on its way now.

If its na just keep the Stocker. If you want to, just grind down the factory imperfections on the inside. Just something a friend did ( gonna do mine this week). Mazda did a great job on the na headers. Spend the money else where.

I just posted this in a similar thread...

"As for the OBX header, I have one on my '91 1.6. It's been on for 7 months (nearly 20k miles) without a single issue. Fitment is good, went in easy enough and still looks good today.

Concerning drone, the stock manifold used to drone between 3500-4200 rpm, or roughly 65-75mph which is where I cruise on a daily basis. With the OBX, that drone is now gone completely. There's also a quite noticeable power/torque increase in this range, from about 3200-5500 rpm. When cruising at 75mph, I can just punch it in 5th gear and the car will take off amazingly quick. Just about as fast if not the same as it used to in 4th gear and stock manifold.

Sure, it may be a cheap header, but it worked out pretty good for me performance-wise. It also improved my gas mileage which is the main reason I got it. I went from a consistent 29mpg to a consistent 31mpg, all logged with my GasCubby iPhone app. If I hypermile it, I can reach 42mpg."
