Description:APS WRX STi 3 inch Turboback Exhaust
[APS WRX-HOE/R1]
Exhaust system design parameters immediately after the turbocharger are critical not only for outright performance, but for optimum torque and turbo response. The optimum internal profiles cannot be achieved with twin pipe or bell mouth pipes. APS has engineered the High Flow Turbo Outlet housing for extreme gas flow and high exhaust gas temperatures which are normal in high performance turbocharged engines. Cast in high temperature ductile iron ensures optimum internal shape and maximum durability under high rpm, load and boost conditions
The end result is an exhaust system that produces high outright power with stronger mid range torque than fabricated turbine outlet style exhausts. All this with improved turbo response (less lag) when running large turbochargers and maximum durability.

This is an excellent choice for a high quality TBE that will last as long as your suby. The assembly is straightforward and displays nothing short of top quality construction. Trimming the factory heat sheild is easy make sure you use it. The extra heatsheild on the cast collector is a good addition. The exhaust note is perfect and almost inaudible after the car is warm with a nice throaty sound at full throttle.

The quality of the APS products was the #1 reason for purchasing this TBE. I have yet to be disappointed with this product even after around 3 years and two cars (04WRX and 06STI). The fitment is clearly an A+ and only requires a simple bit of trimming of the exhaust divorcing wall in the collector which APS says in their instructions is needed for the USDM. Its ductile iron so its not that hard to trim/grind. The look of product on the car is great because it does not scream ticket, unless your WOT :-) I did have a problem with the available high flow CAT with rubbing and vibration against the firewall. This was remedied by doing some simply bending and application of a firewall padding/heat tape. I'd recommend the APS line anytime.
