I am looking for a good set of headers with a y pipe for around $400. This is the one I am currently looking at. http://www.ebay.com/itm/171061811292...84.m1423.l2649 Has anyone used these? How is the fitment?

 

never heard of these, have the hooker shortys on my sbc 305 & have hedman long tubes on sbc 355 on 78 TA, both work great except the hedman's tend to get leaks often/flange is thin, never a problem w/hookers

 

I bought the OBX longtubes, and WOW! These make my car sound like nascar.

 

Do you have to modify anything from the converter back? In other words does the rest of the exhaust stay stock?


Thanks

 

No, I had a magnaflow catback system to go with this. Just for now I have a strait pipe, but I will be buying a high flow cat shortly. As for the headers, you won't have to modify the driver's side header, but the passenger side header may need some modification to get in. You can grind down the a-arm mount or dent in the outermost longtube. I ended up slightly denting in the tube.

 

Does this come with a y pipe? I do not see how the set up of these headers would get over to the factory location of the convertor? How do you like the Magnaflow set up? I am looking for a bolt in set of headers. Hopefully these work if I can get a y pipe with them!!!!


Thanks.

 

They came with a y pipe. They will not hook up to the factory location for the converter. You would have to cut the converter off then trim the pipe that goes to the rear then reattach the converter. I bought the magnaflow for quietness but the long tubes canceled that out. It's not as aggressive as a flowmaster, but the magnaflow sounds good when you get on it.

 

It's too loud to be driven with a straight pipe and an LT4 cam. I ended up ordering a magnaflow high flow cat tonight.

 

Can you give us some measurements on the primarys and collectors .
And did you have any bolt alinement issues on the flange.
Which eBay seller did you purchase from?

 

I'm not an exhaust expert (and i don't mean this to come out the wrong way) but don't headers kinda go off the theory of fast flowing and zero turbulence when the exhaust is leaving the engine, causing it to flow easier and quicker. I know folks would say that denting in the header tube would cause turbulence therefore not good.....just like the intake runners. I had bought some longtube headers originally but found out they wouldnt work without modifying the subframe (smashing in a dent to make room for the collector)
I put the hooker shorty's in my 87 t/a and had no issues at all, i only got the hookers cuz they were the cheaper option when i was shopping for headers 6-7 years ago. they still are working great, just a little surface rust from the 3-4 years of daily driving. thats just my $0.02

 

I probably would have ground the a-arm or whatever was in the way, but a small dent probably won't matter much. Those OBX headers are 1 3/4" stainless, which for the price is a really great deal.

i gotcha, i was just always in the understanding that denting the headers is a big big no-no.

 

It didn't cause any problems at all. I have been getting some vibrations on the driver’s side pipe, which wasn't dented in. I think I installed the motor mounts the wrong way, so the driver's side of the motor sits slightly higher than the passenger side. Because of this, I don't have enough clearance between the driver's side header and the transmission mount. Occasionally, it'll vibrate the area under my seat at idle.

 

Any pix of these installed?

Doug's LT Headers D3321 coated $554.99
Price match at Jegs $100 more for quality headers

 

They are $633 from summit. I don't know if summit will price match, but I wouldn't pay $100 more for mild steel headers when stainless headers are $200 cheaper.

-- Joe

 

Cheap stainless will also rust

 

How do you know it's cheap?

-- Joe

 

Look at the price....a mufflex y-pipe alone for LTs with 02 holes is $350, and its only aluminised. A set of SWs/y pipe are--->$1500...

 

That just tells me american made stuff is too expensive. No wonder unemployment is around 8% Folks don't want to build anything unless they are being paid top dollar.

The chinese turbo header I bought is stainless, of good quality, built well, etc. I've been welding on it for the past two days making alterations and it's nicer than my SLP headers that were made in new jersey.

-- Joe

 

Thats because its "dat-gum good". The guy who made x-product knew what he was doing, and he got paid a wage he could live on.

 

The guy that works at my local McDonald's drive up window does a great job handing me my bag of food as well. That doesn't mean the job is worth more than minimum wage.

If companies want to be competitive with asian markets they need to sell products for a reasonable price. If people want a 'wage they could live on' stay in school and get a good office job.

Were talking about a "Manufacturing" job, not a burger joint job.

Any ways, "you've got to pay to play".

 

Right, and we've been losing manufacturing jobs over seas for years. Americans are greedy and want to much money to build simple items.

From what I can tell, the quality is the same as the turbo headers I purchased which is fine. Better than SLP's.

If you do buy a set, please report back.

-- Joe

 

I would never buy those. I have a set of (used) coated Dougs LTs and aforementioned Mufflex Y-pipe. The stuffs fits fine, no cheap materials and such here.

 

Cool. Well then since you obviously have no experience with the OBX headers, and as such can't distinguish the materials used your comments have no factual basis and shouldn't be considered.

-- Joe

 

Since you don't support U.S workers and keeping the money here, neither should yours.

This is a tech forum, not a political forum. Nobody cares about your personal opinions or beliefs, only factual technical information. You've provided no factual information regarding the build quality or durability of OBX headers, and you yourself said you don't have any. So you have nothing to add to this thread. (which I might add is quite consistent).

-- Joe

 

I've been using the headers for a few months, and they are very nice for the price. They are a decent knockoff to those $1000 stainless works headers for our cars.

 

I've had OBX on my 99 Z28 for almost 5 years. They have held up very well. They have turned a neat looking blue, but no leaks,warping, or complaints. I got a NIB set for my 83, if they hold up as well as the ones on my 99, I'll be super pleased! I also got a set for my Vette for christmas, I look for these to be good too.

 

OBX LT headers > Headmans (HLT) long tube headers.
OBX primary tube 1 3/4
HLT primary tube 1 5/8
OBX flange 3/8
HLT flange 1/4
OBX uses 16 gauge SS
HLT uses 18 gauge S
OBX slip on collectors
HLT ball socket.
OBX comes with Y pipe 2.5 to 3" out
HLT doesn't come/nore makes one 3" out

OBX will be getting my money at the end of the day we just want to go fast without refinancing are homes.
