The OBX I got wasn't perfect, but it was inexpensive, and does add power. I'm happy.... I'm sure those that buy this one will be happy too!

for a stock set-up (catback) exhaust its ok,
but why would u want it w/a 2.25" exit if ur runin' a 2.50" Milltek for example

Some have said it looks like the PILO header - I don't know that but I do know it looks like the header being offered by MTH.
So you have your choice between two designs 4-2-1 or 4-1

I'm comparing exhausts right now and it looks like I might end up with the Milltek at this point, so I think I'll be using the OBX header.
Winter project, as if I didn't have enough already...

Is it just me or does the flange on the header look vertical when mounted? And if that is the case, will the race pipe actually fit to the exhaust if it is on the header? It just looks like if I rotate the race pipe to fit the header, it won't line up to the diagonal exhaust flange...'cause it doesn't look like the flanges are the "floating" kind.
Maybe it will....it's a little hard to envision @ 1245 AM.

hmmm!
..& how are u seein' this again!?!!?

ZRwon, let us know how those 'two' werk out for u!!
that's kool that u have 'two' to fool w/.....
will be lookin' around for a set myself soon so interested on the amount of tone change after the manifold is in place!!!

I have the obx but I modified it slightly. I ground off the part of the flange that holds the dougnut gasket and made a pipe similar to the one in the picture of the latest header. ( the resonator pipe ) Now I have a 2 bolt flange on either side of the cat and a flex just like the stock header and the one in the picture. Also since the obx is 2.5 I made sure the piping I used and the flanges and flex were also 2.5. Runs great and sounds great.
Best part is there is no issue getting gaskets because they are all the comon 2 flange type shown in the picture, a couple bux each and readily available unlike the dougnut that comes with the obx.

Got the OBX header installed at Helix last week. I'm glad Eric charges a flat rate for this -- the job took ~ 6 hrs. Well, some of this time was waiting for the header to cool off after I arrived, and then Eric had to run out for SS welding wire. But I think the OBX header was on and off the car about 5 times getting it to fit. Two of the bolts had to be replaced with studs, and some of the bolt holes had to be opened up.
In spite of this, it is good improvement. The whole speed-torque curve seems to be shifted about 500rpm - in other words, it now pulls as well at ~2500rpm as it did at 3000. Really makes the car more fun to drive. Previously, when I launched without quite enough gas for the clutch release, the engine would bog for a second. No more. It just pulls through. Hills that used to require a down shift from 4th to 3rd don't anymore. This mod is similar to the pulley, makes you wonder why it wasn't like this from the factory.
The header does add a bit of noise at times, occaisonally a resonance in the cabin around 4000rpm. But mostly, the sound is just slightly different, a bit deeper and/or more raspy. Overall, I'm happy with the choice of changing the header rather than the more conventional route of a cat back.

off ur manifold what exhaust do u run, or is this a one nut/ball?
is the drone real heavy to where it shakes the car.
