OBX Long Tube Headers

OBX Exhaust Header 2009+ Nissan 370Z VQ37VHR Long Tube | eBay

Any of You guys is running these headers? their design looks very similar to F.I's (don't mean quality), but bang for the buck, they seem like a good deal if they really are T304 Stainless Steel, what do You guys think?

Don't want to start a brand vs brand contest, just looking for proven facts, their finish seems pretty decent on the pics and a very good price if they can perform near or similar to any of the others LTH's out there performance wise.

OBX stuff is of terrible quality and they just go around copying designs from other company, plus their welds aren't up to the level. So it's a gamble if you get these, and if they you get a cracked weld, it's going to cause you a lot of headaches.

For $500 bucks, it's not a huge hit to the wallet if they don't work out. If I were on a seriously strict budget, I would try them out, but it doesn't make much sense if we are driving new Z's around. The install will cost more than the actual headers, so it would be a DIY for most that buy it. There are used PPE headers I see floating around from time to time that are a couple hundred more dollars. I bought mine coated new from a private seller for $750. Used F.I headers run twice as much as these do new. OBX in general doesn't have the greatest track record, but I'm still not going to hate on anyone who tries them out. 1/3 the cost of the normal going rate for headers is a hell of a value.

Someone buy them so we can see the shortcuts they took compared to what F.I. is putting out. This would be a huge selling point for F.I. if they can pick these apart and detail the differences.

I can say from owning an obx dowpipe on my volvo that i havent had any cracked welds or leaks in 4 years. HOWEVER, your headers will not be pretty for very long. my dp is about as ugly and discolored as pipes get. if u dont mind wht they look like then they will work fine. if u want people to go "badass headers!" when u op the hood, then dont get them.

I had some OBX stuff on one of my Civics. Would I buy it again? No. Is it absolutely terrible stuff? No.

their collector isnt a good one and I wouldnt waste any money on that !!
my guess is it could be pretty much the same as having the OEM header + test pipe.

I would be interested in this anyone out there have these????

back in the day I had an OBX turbo header for my SR20 S14. The fit was good and I never had any leaking or cracking in over a year. On the other hand I knew of people that did have issues. More a matter of consistancy than anything. Quality control is not thier strong point.

As far as their design, do You think they are comparable to FI?

hi!!! i have mine in a 2012 nismo and they fit very good the bad thing is the color change. i take out and paint with ceramic couting and is like new. for the money is good buy!!! and sound good with my nismo muflers. and no service light on.

Have You done any dyno comparison ??

Lots of guys with maximas (3.0 and 3.5 VQ) run the OBX header, it made nearly the same power as the much more expensive cattman header (sort of like FI for maximas :icon17:) for a fraction of the price. I never heard anyone over there complaining about it cracking etc, just that it made slightly less power and like some other members have already said that it discolors quickly.

1.7in is kinda large for the pimaries. I wonder how this affect low and mid range torque.

Not really, in fact they are smaller than the other brands, PPE LTH design uses stepped tubes from 1.75" to 1.875" and Fast Intentions is all 1.75" for the primaries.

Thats weird. All my V8 buddies say 1.7 and larger is only necessary for big block stroker motors. Our engines aren't necessarily on the large side.
