OBX i believe are equal length AKA sound like a honda

 

That may be partially true about the Honda sound w/o the vtec LOL.
You can give it the boxer rumble if you have a good exhaust guy that knows how to route the plumbing correctly.
You will have to manipulate the header by cutting it though.
Nothing like spending $ 300.00 then cutting it to shit...LOL

 

If you look for equal length header for your car, OBX is a very good value, as its similar to COBB equal length header without the COBB's price.

But personally, I prefer the unequal length header, the engine sound is soooo damn great with UEL header on. Besides, you already paid for a Subaru, why not to bring out the character of it?

 

I had an OBX, I hated it. It made the car sound like crap, and the performance gains were not worth it.

 

Honestly, on a NA Subaru you're not really going to see much in performance gains from any headers.

 

^ Look up williaty on nasioc. I seem to recall he does infact have dyno sheets for EL headers.

 

To The OP!

If the OP would have used the search button and searched 'OBX Headers' he would have found:

Come on guys ~ everything you want and need to know is hiding behind the search button...

If I can find both of these in 15 seconds, so can you!

 

It doesn't hurt to have it all tuned, either, which is throwing a couple more bills on top of the ever growing pile.

 

Son, I hear you there. Once you start there is NO coming back! LOL

Here's where I've been so far: http://www.rs25.com/forums/search.php?searchid=1462693

 

I wonder if UEL vs EL yeilds any difference in mpg gain?

 

The header doesn't cause large changes in mpg. I saw about 0.5mpg lower with my setup but 5-10 ft-lb gains everywhere, a little more at the extremes.

williaty has a good comparison between the OBX and Borla headers on the same car. The OBX made more power everywhere and decently significantly so, enough where I wonder to guess if the Borla makes very much over stock at all.

The sound can be greatly influenced by what hardware you run after the header. Don't think the header is the sole thing influencing all the sound.

 

Yeah, I've heard much worse. :lol:

 

Just listened to that vid. Sounds a lot like mine (mongrel cheapo catback on mine tho). No one who's heard mine thinks it sounds like a Honda. If you've heard a Honda with similar mods, there's no comparison.

On the other hand, if you've been around race-prepped flat 4s and flat 6s, you could make a case that the OBX headers make it sound more Porsche-like. Certainly, there's more resemblance there than to Hondas. But hey, I did it for the power, too. MPG is about the same IF you drive it the same (I get 27-28). If you run it redline before shifting all the time with it, it's going to be worse... Possibly it could be improved with a tune/reflash. I don't know.

 

IMO, EL headers + catless + good resonator + cams (correct me if I'm wrong but I think they deepened my exhaust note) = sounds like a race car. I love the deep tone of my idle and the porsche-like sound of full throttle!!

 

DING, DING, DING!!!!!

We have a winner!!

 

But loud. :lol:

 

hahahaha for sure man. Even with the supplied OBX resonator and a 24" resonator on the midpipe my car is crazy loud at full throttle.
