Default EJ25 Header Comparison - Weights


Daddy? Why are you standing on the scales holding those weird looking peices of piping?

Before our installation after the Local Solo II Test-n-Tune this past Saturday, we decided to get all three headers together for comparison as well as get some weight info for those autocrossers who care about weight.


Well, results were as expected.

Borla exhaust Manifold - 10 lbs


Stock exhaust manifold - 13 lbs


TWE Super Stock exhaust manifold - 15 lbs
*mild steel version, ceramic coated inside & out 2000 F


Now.... don't let a few lbs sway you. Hands down the TWE is phenominal for performance. We ran the Boral at the TnT and then the TWE the next day at the auto-x.

The TWE makes 1st & 2nd just go by so quick. Even in transit 3rd was impressive. The car is noticably quicker all around.
Low end is improved, Midrange is improved, top end is improved. We were truely amazed. Sadly we won't have time to dyno these different headers.
We hope to be on the Dyno this coming Friday before the Central Region Subaru Challenge in order to get an idea what kind of torque & power curve we've got.

Car runs smoother, idles smoother and all around just accelerates and moves so much smoother. Sadly the Subaru Burble is gone, but when it comes to performance, some things have to be sacraficed.


Ahhh! I see, it all makes sense now!

Thanks - Jon

I'd really like to see some dyno charts. I'm looking to buy some headers in the near future and want to get the most out of them. Although I'd really like to keep the mean subie growl, but I could live without it for significantly more power.

great info.
when you were swapping headers did you replace the gaskets?

Paypal me some money and we'll considering putting them both through the Dyno paces.

It's a lot of work and obviously not worth it as the TWE noticably performs better than the Borla and it isn't some ill calibrated butt dyno or placebo effect. I'm very critical and my butt dyno is highly sensitive.
