You didn't, but thanks for letting me off the hook publicly, anyway! As I said in the PM, it's a great photo! Not many people can make a header look beautiful but it was your photos that sold me on the ceramic coated OBX in the first place. I liked 'em so much I'd saved 'em to my documents to pass on to my local buds on MetroplexMINI & quite frankly had forgotten where I'd pulled them from...

I just wish I knew what to advise our Australian friend, here...If he shortens the primaries to get rid of the compressed portion of pipe, I'm afraid he's going to have fitment issues, not to mention performance. I know the reason we liked the thing in the first place was that it was virtually a SuperSprint header w/ a rock bottom price. I got mine off of Ebay, too, so I don't understand the difference. Maybe someone decided to change the design to further cheapen the cost of manufacturing? Hard to believe that such a pronounced difference would be a manufacturing accident or "defect"...

Dude, this NAM your going to have to work a lot harder to be considered an ********* .

Add me to the OBX header list. I love it. OBX + one ball = nice tone and growl. Don't feel too much difference on the low end, but midrange rpms, it feels freer. What I mean is if I do, e.g., rev matching (double clutching), the rpms shoot up way quicker than with the stock header. So I suppose this translates to better throttle response.

I did the install myself. All went well, except the stock cat was WAYYYYY too big to fit between the header flange and the flange leading to the rest of the exhaust. I had to cut it up and get it all welded back together.

Double clutching? Do you have a dog box?

Nope, stock gearbox! When I downshift, I raise the rpms for the split second the car's in neutral between gears. Isn't that double clutch? Maybe I just mean rev matching.

Hey anyone have any idea why my stock cat was too big to use with the OBX? I'm puzzled by this since so many have used this combo. I've got a stock one-ball exhaust from the cat on back.

Thanks

This makes no sense? too big? As you point out many have done this including myself. The back end of the cat remains untouched and bolts up to exhaust. The front end of the cat is cut basically at the cat and the supplied OBX flange is welded on. Another way to put it is once the OBX header is installed you measure the distance between the OBX and stock exhaust. You take that measurement and measure from the back end flange of the cat and measure forward minus the supplied obx flange. Cut, weld on flange supplied = the length between header and exhaust. Bolt up.

Ahhhh!

I agree, it doesn't make any sense. I just went out and measured again. If I bolted the stock cat flange to the exhaust, the front of the cat where it hits the obx flange would be into the body of the cat! If I cut the cat at the closest I could without getting into the body of it, that would meet up at the obx donut gasket, which wouldn't work.

Ug. Only me I tell ya!

I will be joining the OBX Header club in a short-while. I just received it as a christmas gift sooo here's a picture of it just out the box...



I can't wait to get it installed.

Your in Miami - who is going to install it?

Here's a photo of my set-up.
Also using the One-Ball. Sounds great!

I'm baffled - the only thing I can imagine is that your 1-ball pushed the center exhaust forward somehow. It appears you just removed about an inch? here are pics of the set-up - first page midway down. https://www.northamericanmotoring.co...&highlight=obx
