DC sport. End of story. Check my sig for mods and at the bottom was my dyno run a few weeks ago.

Cya

 

Right now OBX has the best header for the XB. PLAIN & SIMPLE!!! The 4-2-1 will out perform the 4-1 all day. Plus you wont have to wait untill 4000rpm to feel the gain. A buddy of mine is running CAI, DC 4-1's, and the axle back DC. He said he felt more power in mine and all ive done so far is the 4-2-1 and the CAI. Beleive it or not i put a flowmeter on both our tailpipes and the Aftermarket axle back is only flowing about 20cfm better than stock. All your really going to get is the fart can sound. If your into that.

 

you are high..........

 

OBX is crap. 4-2-1 doesn't make that much more whp than the 4-1 on a 1.5l. You are high. If you live near me i'll race you just to prove it.

 

....On a track of course!

 

Once again, the know it alls throw their 1 cent in. If you want to talk race, my 95 mustang goes 9.1's in the 1/4. And bike is even faster. Ive been working for a speed shop for the past 4 years, ive got a little knowledge id say. How many cars have you built from scratch? Probably not. Lets see, how many sets of OBX headers have you owned, Probably none. How many times have you traveled over 100mph, maybe a few. If your lucky.

 

Anyways......

 

how many times have I traveled over 100? at least 200 times.

i don't care about a 9.1 secon rustang. we're talking xb's here. and who has been running certain parts versus other parts on these cars for over a year and a half? I have. say what you wish.

how many set's of obx headers have I owned? none why? cause my bud bought them for his 2002 honda accord v6. worst looking headers I have ever seen and i've laid my eyes on at least 50 different mass production headers for different cars. total crap......

oh wow a bike faster than 9.1 ummm yeah bikes aren't that hard to make fast.

 

So wait, youve never owned a set of OBX yet your ******* them because your bud bought some for a honda. Im sure they are identical to the honda headers. And whatever man, i sell more performance parts in a month than youll lay your eyes on for the rest of your life. Figures youd be some smug pric from CA. Its one of those times like when your on the phone with someone and you wish you could just reach out smack the crap out of someone. Lucky for some i guess i can't.

 

I don't need to eat a steaming pile of feces to know that it will taste like sh*t.

 

Here's the thing. You also can't discount the power an OBX header makes until you've tested it, and I don't mean a "butt dyno." Dynoing is the best way to test the horsepower.

It is possible that OBX might make more power. But only a dyno will be able to really tell.

I don't see why it would be impossible for the OBX header to make as much power as another header. Until I see a header shootout, it's all speculative.

 

i've driven many different headers on the same xb and the buttdyno is not the best but if you can't hardly feel the difference in any of them. ....

and dyno's arent that accurate. different dyno , different time , different temps , different results......

 

Agreed. However, there isn't a better way to test hp. The best way you can do it is try to keep the variables constant.

 

no I never have owned one. why? cause the first set i had seen from them was horrible.. why would I want to own one after that?

i've installed a set of obx on a cutomers car. the quality of the welds and the flanges , the piping were not up to par with my megan racing. and the megan racing is just a good cheap header it isn't the best by far. but it has the same result for less money....


i'm not a smug pric. and right now you swear to everyone on earth that you know all cars better than I do cause you have a fast bike and a rustang..... congrats. i'm sure you know a lot . but don't you dare discredit me on the cars that I know INSIDE and OUT.

Nothing like threatening people over the internet. I bet you feel a lot better about yourself eh ?

awesome you sell lot's of parts. i've sold lots of parts before , i've installed a lot. and you are being the *****.....


dude. ask just about anyone about what their opinion on obx is........9 out of 10 will say it is crap....

from first hand , installed part , part ownership , or word of mouth. however you slice it that's a lot of bad wrap for a company..... about as bad as apc.

and I installed the honduh ones. might as well have owned em. If it was me who bought them I would have returned them he did not. but he sure as hell wanted to after 20k miles when they were leaking from bad welds......

 

I never said the obx doesn't make as much power it probably makes the same give or take 1 hp. but my experience with their headers , intakes , and all sorts of other random crap parts they've put out has all been bad so I would never buy from then again.

 

obx does make a 4-2-1 and no it doesnt make more hp but it does make more low end tq. Not everything obx makes is crap either just most of it.

 

Okay, first of all lets not talk about bikes. Totally different concept, big difference between a 2,000lbs car and a 500lbs bike.

I've built a gsr from scratch in terms of starting out with a completely stock car, the xb for everyone was stock before starting their own projects. So you worked at a speed shop for 4 years and? I've proved wrong a few shop owners/workers, one had been doing it for 10 years. Just because you do it for years does not mean you've actually picked up useful information along the way. It just means you are probably decent at least at what you've been trained to do.

Also, did someone say testing an obx header? I've seen one video of an obx header (4-2-1) on a xb. He had i/h/e, i think borla exhaust and injen intake but i could be wrong. He pulled 103whp (manual). I'm pulling i/h/e 96whp according to dynojet on my auto xb. Another manual i have seen, with a different set up (not sure what he was running) pulled 106whp (roughly) with just i/h/e. Sure, its only 3whp difference if i remember the numbers correctly, but thats not even the point. Quality of the parts make a difference in the long term, and obx doesn't have quality. No company sells quality headers for $90-$110 brand new unless they are on sale. Especially a 4-2-1.

Then you have MMW that jacks up their price from weapon-r. Weapon-r is better than obx, by a long shot but i still wouldn't buy their headers either. Especially with the $350(?) price tag that MMW put on their just because their name is on it.

 

Let me share some of my thoughts on this matter

Let just think for a second that where does the exhaust gas travel when it exit the engine. It will flow down the four lines of the header and then collected into a point, small part of it will be recycled back into the engine to power the brake and other things while most of it will flow into the catalic converter. From there the clean smoke will flow into your mufflers and finally exit the car.

So say if you're to buy the best hi-flow header and put it into your box. The problem is that it still have to go through the OEM catalic converter (which I think you have not change, and it's illigal to do so)

So what good is the Hi-flow header do if you are gonna mount an OEM restricted catalic converter at its neck? It's like you put on an oxygen mask but haven't clean out the boogies in your nose.

A word of caution about the manufacturer claim on horse power increase, it'll never represent the real world. if the header doesn't perform any better, they modify the test so that it will. Personally I love to see a different people, who are not affiliate with the manufacture, do the test. You will be stunning how much they tricked you.

Well, I didn't buy my xA to get the horses, but if I was, I wouldn't buy the xA in the first place. Why spend so much money modify something that in the end still isn't what I want.

Think about it....

 

i was dyno'd at 96whp, obviously it works.

I could go on now and explain, but this is pointless.

 

the only way to get a true dyno reading is an engine dyno. wheel dyno results all vary. you can run 3 runs and have 3 different results. the time of day and how things are setup can all affect the results.

any header that is equal length will give the same amount of power no matter what. the whole thing about a stock cat being restrictive is kind of true but also bs at this point. it really doesn't restrict that much flow. proper exhaust setup doesn't alow for exhaust to be recirculated back into the engine the exhaust system should be a negitive pressure zone so it flows from the engine.
