The stock tune is dangerous, and i would suggest at least getting a retune right away. Lean tip-in at the trq peak is very bad....trq peak is the most likely area for detonation to occur.

been there and done that. not hating, trust me. GREAT car!

Now this car you are creating is an absolute monster. i love the dedication to high quality with a track comparison. that is a great measure of understanding gains and standing behind them. kudos.

looking forward to the track results!
Not one squeak or noise from the bushing, chassis or suspension. It's pretty amazing that response is improved like this, with no increase in harness at all. Hats off to Whiteline for some amazing products!

We'll have a more detailed install and review of Whiteline very shortly.

When you say 3" to 2", you mean single 3" to dual 2" right?

LOVE that paint color, wish it were available on the 2011 WRX though.

I'd doubt they'd neck it down to two 2 inch pipes, two 2 inch pipes would create more backpressure because
there's less area to flow through.

a = pi * r2

In this case: a=3.14159 * 9 = 28.2743343 for a single 3 inch pipe


versus a = 3.14159 * 4 = 12.5663708
* 2 (for two outlets) =25.1327416, which is less flow than a single three inch outlet.

I think what he meant was that they will be using a single 3" pipe, then divide that into two 3" pipes at the Y in the exhaust.

That's correct. I would suggest getting a tune as soon as you are comfortable with your engine break-in.

Ok, we just wrapped up our prototype 3inch exhaust. We are still making some changes to the system, but I want to share a quick teaser dyno. On the first pull, I realize just how much trq, spool, and power we were missing and the results are nothing short of spectacular. Boost level is the same on both runs, and I think we're one of the only shops to post boost curves. All in the interest of sharing as much as possible with the community.

The only change is we switched from the stock exhaust to our 3 inch exhaust. I did not adjust timing, but I did have to ADD additional fuel because the new exhaust naturally resulting in less backpressure and more efficiency from the engine.

400rpm earlier spool which shifted the power curve 400rpm to the left
50ft/lbs peak trq improvement and 21whp peak improvement.
But even more telling, is the 100lb/ft trq improvement in the midrange

That said, the car as it sits now is actually decent in the midrange and a lot of fun to drive around town. Certainly not a road racing turbo by any means but much more tolerable than I would have expected with this big PTE 6765. I've got a bit more tuning to do on pump, but so far these are the highest numbers I've produced from 20psi on a 100% stock engine STi on our dyno. It would be nice to hit the magic 400whp on pump. Good stuff.

Shortly after that, we'll do some before/after testing of the one-of-a-kind AMS Prototype Intake Manifold.

Throw the AP stage 1 ots on the car, then follow the engine break in procedures, change your oil, then go have fun. Don't want to break your car.
