Default Pacesetters versus OBX

Looking to purchase a set of headers in the next week or two.

Out of the Pacesetters (coated) and the OBX, which do you choose and why?

OBX= 1 7/8 Pacesetter= 1 3/4 So IMO OBX all the way.

obx is stainless as well. i went pacesetter and am happy with fit and finish and my car made ok power. if you have FI or H/C the 1 7/8 will find you a few more ponies.

If you go OBX you probably will have to make some clearance around the steering shaft otherwise it may rub. This rub will be worse with sagging stock mounts. If you are going to do the headers this is a good time to get rid of the stock motormounts and upgrade to Revshift, UMI or CS. I thought since the dealer replaced my stock mounts under warranty 30k miles ago (mostly highway) I was going to be OK and within a month after doing the headers I took it all back out to replace the motormounts.

I have the Revshift motor mounts waiting to go on. I figured before I tackled that, I might as well order headers. Will probably go ahead and do new plugs/wires while I'm at it.

Thanks for the input everyone!

OBX quality is top notch. No complaints here!

The real questions is...what are your plans for the car?

1 3/4" are better for your basic bolt on/DD V.

Where are you will see better gains with the 1 7/8" if you plan on doing H/C/I or F/I to the V.

I had 1 7/8" Kooks on my 2007 V, and a buddy of mine had 1 3/4" on his 2007. We had identical mods, and on the same dyno in similar conditions, I made 357/370 and he made 365/375.

I'll be doing something significant in the next year or two. Haven't decided if I'm going to do HCI or go straight to a Procharger though.

I think I'll definitely stick with the OBX based on everyones input.

It's not like the 1&3/4 is going to choke the car if you end up gonig forced induction. they flow what, 15% less than 1&7/8 primaries? I say whichever one you get the best deal on. Even if they are both stainless, chances are they will still rust if you live somewhere where they salt roads or something.

I have the OBX on mine and had an OBX downpipe on my supra. People hate on chinese products, but they have come a long way in copying others work sometimes. The OBX exhaust stuff is great!

Exhaust manufacturers are crazy. $1000 for a catback? Ridiculous. The mufflers retail for $150 each. Crazy mark up for some bent pipe.

Yeah, if I come across something used between now and when I order, I'd jump on it, but new vs new, I think the marginally more expensive OBX are worth the stainless and larger primaries.

If Pacesetters were offered in stainless it would be an easier decision.

How bad was the clearance issue? I'm thinking I want to order the obx by this Friday and already got new revshift mms. I was looking at the pacesetters but want cats. I know you can get some universal cats with the pacesetters but there's a lot more fab work. Has anyone not had clearance issues with the obx?

That is exactly what I am doing right now. Waited to get all the parts and just about to start the install!

I like to hear that!

you can see the mods in my sig, so I am hoping for another 5-10 rwp with the headers, motor mounts, plugs and wires.....

I went with Coated Pacesetters due to the clearance issues, I have heard with the OBX on the Vs, PLUS I got them on a scratch and dent from Amazon for $300. Not a damn scratch and dent anywhere to be seen except on the boxes. lol

About to coat the insides as well.

Which ones will bolt right up to the xpipe that is hooked to the end of the factory cats?

I believe the Pacesetter will iirc.

If you buy the "off-road" extension, then it bolts to the stock pipe and you can clamp it to the headers outlet, but most people weld it.

There is an install thread on here for the Pacesetters that will show you photos.

OK cool. I have somesort of x pipe under there hooked to a magnaflow CB I just want whatever I get to end where the factory ones did.


Also will a handheld tuner let me turn off the rear o2 sensors or where can I get the Mil eleminators? How good are mail order tunes and so on?

Well, you have an aftermarket cat back so no telling.

Get the O2s tuned out, don't F with a handheld or the eliminators.

Save the money and do it correctly the first time.
