Default 08 STi: 322awhp/362awtq on NEW Titek Titanium Catback + Titek Unequal Length Header

UPDATE: Dyno vid available in HD at the bottom of the post!

First off, I would like to thank Carlos from Ramini Sports and his distributor because if it wasnt for them, this would of never happened. Also, thanks to Danny from "Some Assembly Required" for his expertise in the entire Subaru powertrain.


This is the only one at the moment anywhere (from what I was told). The fitment and construction is perfect, from the welds to the flanges where it bolts up with the downpipe etc. Best exhasut I have seen till this day.

The entire catback exhaust does weigh a mere 14.5 lbs, verified by me. My camera was broken, and I had just bought a new one minutes before the install, so I was lucky enough to get these snap shots of it, vids, dyno vids and a chart of the best dyno run we had under such limited time. There will be more review to come (inside the car, drive by, etc).

I am also including some pictures of the headers which are very impressive and very high quality.

Parts List:

-Titek Full Titanium Catback with Titek Stainless Catless Downpipe
-Titek Unequal Length Headers (4-1) with uppipe
-AEM Cold Air Intake
-Perrin Inlet Pipe
-ACT Streetlite Flywheel
-Mishimoto Radiator + Thermostat
-Cobb Tuning Heatshield
-Cobb Tuning Accessport
-Protuned by Carlos (Ramini Sports)
-STOCK TURBO
-STOCK INJECTORS
-STOCK FUEL PUMP
-STOCK INTERNALS, CLUTCH ETC

Dyno Info:
-Dynomite Dyno
-322 awhp 362awtq
-87 degrees ambient temperature (44 Humidity)
-11.80 AF Ratio
-22 psi taper to 19.5 psi at redline

Onto the pics!



















The tune will be smoothed out a little more with more time...

You'd be surprised, but the Titek, GT Spec, Tomei, HKS, and even some other brand headers in unequal length, look IDENTICAL.

Wow your stock turbo holds 19.5 at redline? That's very impressive, especially with the stock internal gate. Great looking exhaust work too.

Well done. I have no idea what a Dynomite Dyno is but I don't think a 2008 STI could hit those numbers with a stock fuel system on a Mustang dyno.

From what I was told the Dynomite dyno isnt as good as a Mustang, but it reads close to it, definitely reads lower than a dynojet, I know that for sure (supposedly about 10% less than a dynojet).

Yeah, believe me everything on the list was done in one day and the pump just wasnt able to get done. I have it already and I have a lightweight crank pulley too but it will all go in soon. I know I need the pump, my injectors are just above 80% load...

There is absolutely no way you are holding 19.5 psi to redline on the VF48. The dyno graph also does not reflect boost holding to that level. If I were to guess, I'd say that you are making no more than 13.5-14 psi by redline given the large (and typical) falloff in power towards fuel cut. Also Dynomite dyno can be user calibrated to read anywhere from very low to very high. The two that I am familiar with in my area both read the same or a tiny bit higher than my Dynojet.
