Actually says gen 2 & 3. The pictures show a dog legged gasket. I suspect that like Heddman they incorrectly state that they fit gen 2 as well. While they will physically bolt up to a gen 2 with rectangular ports they will not match correctly. They probably do not know any better.

What would the Chinese know about AMCs? They're just copying someone elses product.
How fitting, Chinese headers on an "American" Motors.

Had a look at their other AMC items. They have 3 of these same items (part #12077) being sold with 3 different descriptions. One of the descriptions is for 1966-1970. This seems like it is the seller that has no idea.

I sent two different e-mails,one to e-bay site and one to the obx site.The e-bay site responded only,"They will fit all gen2 and gen3 engines."That was it,with the word all underlined.No application for vehicle fit.Evidently they don't know or possibly worried about a copyright infringement.I may check on a send and return policy.I don't think I should be out anything though on a new part that might not fit. ------------- 1972 SST, 2001 MERC., 2008 CROSSBONES If it moves,it's going to break!! |

Here's a couple of threads on what the Chinese are doing.

Enough people complain about header leaks. I can imagine the quality these cheap Honda knock off headers are.

I just looked at the feedback on their e-bay site,most of the negative I took time to look at was about poor quality,bad welds,wrong fit,and wrong lenghts.Click on their store policies and they suck too.Bye bye OBX.I guess the best junk China has is the ones they fish out of.I want my job back!!!!I'll check the threads.Thanks!!!! ------------- 1972 SST, 2001 MERC., 2008 CROSSBONES If it moves,it's going to break!! |

Yep, sounds par. What's funny is, I see these headers seem to be popular with Corvette guys.
Lets see, I have a $900,000 car, I make 50 Billion a year, and I want $19.99 headers. Talk about penny wise and dollar foolish! Gave me a whole NEW opinion of Corvette guys.

I have a set of OBX on My Subaru. They are O.K. but I think the quality of the Heddmans on My AMX are better. ------------- 1970 AMX 390 5 spd full Control Freaks front and rear suspension 2014 E63 AMG-S wagon 1965 Austin-Healey 3000 MK III |

I just put a set on my 02 F150 Lightning. They seem to have nice thick flanges and everything looked good on my set. The gaskets they sent were a JOKE so I bought a good set to use instead. They were a pain in the rump to install but so is everything on a Lightning..... -------------

I have a full OBX exhaust on the 98 Altima, about 4 -5 years old and the welds are cracked around 3 of the tubes were they meet the flange that bolts to the head. They cracked between the weld and the flange, not between the weld and the tube. I contacted the seller about OBX's lifetime warranty and was asked if I sent the card in, of course I did. Obx says the seller should do the exchange, the seller says OBX will take care of it. I been busy so I am just driving it, they only tick a slight amount. Fit is stupid. The 4-2-1 that we put on is flanged where the 4 go to 2 and they turned the flange in such a way you have grind a 1" by1" curve out of one of the webs on the block! All they need to do to fix it was flip the flange to 180* but they did not bother and they made those headers for a very long time. They also have an A.I.R tube and they missed it by 2-3"s, You have to gently start the threaded nut and force the header to go down and align with the ports. Hoping the tube does not kink and the threads don't strip. Last you have to snap a web off the back of the Alternator for clearance. No way would I buy a set at full price, even then I'd only put them on something that sees very limited use. They'd probably hold up better if wrapped and silicone painted, but that kind of kills the whole shiny thing. ------------- Wrambler 69 AMC Rambler 4.0L, 5 speed 2015 Grand Cherokee Limited 2019 Chrysler 300 |
