Judging by your analogy, no wonder why you would think that.

Peak HP on one header vs another is nothing more than a gimmick. Each header was done on different dynos, different temps, and elevations and etc more than likely. Only way to take them head to head like that would be if a magazine or something sat down in a controlled enviroment and test them back to back or something.

You want to check the BASE dyno aka stock run, vs what it did with a header only to see the real gains. Again PEAK HP is not the over all goal but more so the gains in areas the car needs it, like the torque dip and down low. Peak power is nice, but doesn't help get you out of corners or away from the stop light.

As far as warranty goes, the only way to be sure you keep it intact is to keep the car 100% stock.

No independent dynos of the ofh..... I would suspect that the supplied ones will paint the ofh In a good light.

They could be closer but I doubt it.

Are you suggesting that because modern cars have more parameters to adjust therefore it's not related?

It's much easier to swap tunes. They have less reason to check or even be able to notice it was tuned than showing up with a header or the stock on with clean spots or no heat shield.


ECUs are locked because they can be.

To OP -- Thanks for the review, it was because of this review that I purchased this header instead of the JDL one.

I am awaiting for mine to arrive now from their manufacturer =) hope all is well so far!

Glad I could help.

Everything is still great. I have about 250 miles on the header now, and I don't think I've listened to the stereo yet! Performs great. Sounds great. To me it seems quieter on the highway and definitely quieter when coasting downhill in gear.

You won't be disappointed.

I ordered my uel on Monday and the rest of my exhaust on Tuesday. I'll probably install it all at once in the fall when I get the header. Gives me more track time in my stock brz. Which is not a bad thing.

500 Mile Update:

No torque dip issues after more than 500 miles. Power is still seemless.

Butt dyno? Or did I miss a post where you had the car on a dyno? I'm not trying to troll, I'm just curious to see how you confirmed the dip is gone.

Honestly, just butt dyno. You can feel a difference in daily driving. I'd like to get to a dyno for everyone, but I don't know any in the area.

All the dynos to this point have been immediately upon install which shows no/less dip. I just wanted to confirm that 500 miles later, the car feels the same, for those that had ECU concerns.

How are your engine bay temps? From what I understand yours is not coated. After a drive is it scorching hot?

It's not coated. I'll have to check for you. I haven't noticed any ill effects or noticeable warmth.

I'm also not in the warmest of climates. It hasn't been over 60 yet in Pittsburgh. Those in the south may experience a bit more heat.
