Agency power header only - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Yruyur · 08-16-2012, 10:01 AM

Anyone use the agency power header only? Very curious of the sound difference. Is it going to hurt performance without a tune? Not going to the track just want a little more sound without the coffee can sound. A little more power would be nice. I have Johns ecutek coming as well.

I would imagine that with just a header and the rest of the exhaust stock that you would still see a sound difference and at least SOME extra power. Your deleting one of the cats which should give you a few more ponies and a little bit more sound. and the header is a lot less restrictive than the stock (being that is smooth stainless steel). Just my 2 cents.

Here's a video I took of John doing a dyno run of an otherwise stock FRS except for the Agency Power Header and his tune. His testing has shown that the header may not help much, if at all as far as power goes.

Thanks for the video! Lots of dyno noise. Would love to hear the idle, fly by, in cabin as well. Sounds better from what I can tell.

One of the cars Visconti used for tuning had their header on it. he said it didn't do anything for power.

Header doesn't do much on its own, the noise changes a little, you can hear more of what's going on with the motor, but IMO it doesn't sound good running the header and the stock exhaust. Could you specify what you mean by you have johns ecutek coming?

Is he coming out to tune or is he sending the stuff with basic tunes?

Yruyur · 08-16-2012, 04:59 PM

He emails the tune to you.

I believe you can do some data logging and John will then adjust the tune accordingly.

Correct. It also includes the future launch control update, and i believe FFS and auto-blip, when they become available.

You can buy an E85 tune as well, if you have that available.
