Hi everyone... I wanted to provide some info on the install/thoughts on my install of the APS TBE that I bought from RallySportDirect a couple weeks ago. The product info is APS WRX/STi 3 inch Turboback Exhaust (http://www.rallysportdirect.com/shop/aps-wrxsti-inch-turboback-exhaust-p-951.html).

The install was pretty darn smooth. The biggest pain in the can of the whole thing is, as the directions stated, that the downpipe must be cut/ground down to a notch that is marked on the area that connects to the turbo itself. It says it is due to the product being both marketed to the JDM and USDM areas and they didn't want to make two of the same product when one can easily be modifed if you have a cutting wheel/grinder and a metal file to smooth out the edge that is cut. It took all of 5 mins to do to make sure the cut was smooth as slik.

Once that was done, the bolt up was perfect including the easy connection to the OEM exhaust mounts. Under real bumpy situations (whoopie for Chicagoland highways!) the exhaust has not rubbed or knocked the underside of the car.

Since there is an EGT hole on the downpipe, the TBE comes with a plug for the whole if you wish not to install an EGT gauge.

With that, when putting back your O2 sensor in the exhaust, make sure you get a mechanical CEL fix to space the sensor from the exhaust flow since you will throw a CEL if you do not have ECU management that will defeat the code. Personally, I did it since I didn't want to fry the sensor and pay for it down the road later. The CEL fix is available at RSD for $30.

Hope you found this info helpful. If you have any questions, post em up or PM me and we'll be good.

i wonder what the difference in sound and performance are between the aps 3' turbo back and the 3.5' turbo back exhausts...? does the CEL go away by itself with the 3.5'aps because i've herd of it with the 3'

yeah i knew boost creep would prolly be an issue with the 3.5, but i thought that the accessport would be able to take care of the boost creep issue. does your 3.5aps have a cat? because the cat should make the boost creep less of a problem if i am correct..

Cat dont make a difference,I had a Cobb catted DP and had creep,so I ported the turbo,it helped but was still creeping to 22 psi! So I decided to go with a cattless APS 3" twin tip,first off its a bit loud for me ,I then got a protune which finally resolved the creep! The car put down 305hp and 328 tq its an animal,gets 24mpg(w/o beating on it) and runs very smooth,going to Limerock in Oct!!

Bump to see if you have had any boost creep with the 3" APS TBE Since you installed it last August?

I just installed the APS 3" with high-flow cat. Sounds great, no droning on the freeway. I just installed a Defi BF boost gauge today, was going off the AP for a couple days but that was maxing out, as the Cobb AP will only read up to 18.4psi. With the Defi I am getting hitting 19psi....Is this Normal? The map I am running is the Stage 2 ACN91, since I am in CA. This map is supposed to hit target boost at 18psi +/- 0.7. I figure 19 isn't too far off. Any feedback?

I haven't had any boost creep issues. I have cobb AP with APS 3in catless turboback. I did have boost creep with the OTS ECUTEK but not since switching to COBB AP
