Whew. Good. Thanks for pointing that out, I must have missed it. I am sure it would fit my car, just not the budget.

I am sure it would go on my 05 OBS as well, but then again, not for the price.

Your 05 OBS can fit a Borla rep for less than $200.

Cool. I thought the header designs were different between the P1 EJ25 and newer models. I was under the impression the older models used a UEL stock header and the new ones used more of an EL design. I'll have to look.

None the less, I'll butt out. This thread doesn't concern my cars (after all), and I don't want to hijack/not contribute any more then I already have.

later guys, GL with the new design.

Yep, that's about what mine sounds like. Mine's not quite as deep because I still have the stock muffler on it, but it has that same pattern of sound yours does.

Would still rather have the boxer rumble. Even if it "doesn't sound like a honda"

lol. Well said. I do concede, it didn't sound nearly as bad as I was expecting. As someone else stated in a borla vs obx thread, doesn't sound like a "honda" but doesn't sound like a "subaru" either. I think you know what I mean. Personally I would take the extra power over the rumble, but its not about what I want, its about what the community wants.

i absolutely cannot wait. i purposely bought a 2.5i for a DD. my whole point in working on this car was to make it look good and sound good. im missing the "sound good" part because no UEL headers. if i had to, id pay up to 700 for a UEL for my Forester. i cant not freekin wait to hear sound clips and be reassured that it is fully bolt on and NO CEL's!

thank you for all the info you have given us and i am looking forward to getting more info along the way.

In all probability, it'll throw a P0420 DTC due to the increased heat loss. With how sensitive the 05+ cars have become, it's nearly inevitable.

Would wrapping / coating help this product not to throw a CEL? If so, what products would you suggest that do a good job?

I had my Borlas coated with JetHot and still got the CEL. The swaintech coating I'm using on my TWE header is far more effective, but I suspect still not good enough. It's possible that wrapping the header might be sufficient, but the wrap will need replaced often.

Best solution, do what I did, have a local tuner edit the map in the ECU to remove the P0420 DTC permanently. I have not had an issue since.

Have not had an issue or have not thrown a code. Two different things.

Dei heat wrap and high heat spray before and after wrapping. Ceramic costing may also help keep more of that heat in.

Or do it yourself


Ok n00b with pubes question. How hard would it be to unbolt my stock header and bolt this bitch up? Should I expect header bolts snapping etc?

Use an impact wrench and they'll come right off. You'll need to be wearing chem lab goggles or ski goggles though as a staggering amount of tiny bits of rust and other crap will get into your eyes. Believe me, being strapped into a head-vise while they use a cotton swab to remove rust slivers from your cornea is a BAD night.


The 06+ cars seem to be getting different studs than the older cars and the anti-rust coating on the new studs is crap. Plan on replacing the studs and nuts. The old (better) studs are 800910390 while the new (crap) studs are 800910550. The old nuts are 902370009, the new nuts are 902370010.

Hahah umm that post was useless without a video! (thanks for the part numbers though) Impact wrench? I wish I had such a device! I live in a second floor apartment with just a parking space. I would give my left nut for a garage to use such tools in

The P0420 is far less likely to occur with the new UEL design. Heat loss would need to be extensive and cat light off temps shouldnt drop much at all after it is achieved, given the cat location relative to the exhaut ports and velocity of the gases. Fast moving gases retain heat better than slow moving ones but they dont transfer that heat to the surrounding environment as well.

The Delta of the cat will be lower due to higher ambient temps caused by the primaries. However I would wrap mine to take out a little insurance against that damn CEL. But honestly I would just pay a tuner to adjust the acceptable emissions values

EL vs UEL doesn't figure into it.

Also, the Borla reps, which are UEL, fairly consistently cause the P0420 DTC on the 05s and the few newer cars that have switched to them.
