I've had my obx's on for a year and a half and 35000+ miles. The only problem I have had is one of the plugs for the extra o2 sensor bung fell out so I bashed the end off an old o2 sensor and threaded it in there. I never welded my y pipe like mentioned above either. I guess one of the clamps broke too shortly after I installed them because I over tourqued when I retourqued them. It's still on there though and not leaking. They haven't rusted either, they just turned a bronzey colour.

 

Also beware of the 04+ 4WD model OBX's because my buddy bought a kit for his 05 and he could not bolt up his front drive shaft or even come close to bolting it up because the runners and collector were RIGHT in the way. And yes his was a 4wd kit, even said on the box and a sticker right on the header itself, I don't know if they screwed up on packing it or what happened

 

May be they screwed up packing, about a month ago I bought Roush front shocks and they sent me the rear shocks, so yes people make mistakes. So if I run OBX 4x4 kit with out my high flow cats will I loose torque with out cats and just using resenators?
Do the OBX come with sensor plugs? I delted my rear o2 sensor with a programer. I still can't decide to go with OBX or PS LT. Great info on this thread. Please keep up dates on this topic, there is alot of people who will need this info sooner or later. Any one else who have used Pacesetter LT headers, please leave feed back.

 

you wont notice any difference in the low end. i didn't, with running just the resonators. but seeing how you got the high flos already you may want to get them burned in there, your choice. If you notice any difference you could try getting them reinstalled and see if you notice any difference.

 

Anyone interested for doing a group buy for the OBX headers sometime in January?

 

id be interested i also talked to someone on a ebay store and he told me the best he could do was $560 shipped maybe we can get it cheaper

 

If we can get more people interested I am sure we can!

bumping this back up with edited first post...

 

What's the exact setup you got going here?

I know its OBX Longtubes and resonators but what aren't you telling me here?

 

hes got the same as me basically, 18" magnaflow dual in dual out with internal X pipe and his is dumped after the rear axle, while mine is out after the rear tires.
