COBB Tuning SS 3in Turboback Exhaust
Subaru STI 2015-2017
Features & Product Details
An upgraded exhaust system certainly wakes up any turbocharged vehicle because it lifts the restraints and limitations of the factory exhaust system. This is the COBB Tuning Subaru Stainless Steel 3" Turbo Back Exhaust System with a 3" Stainless Steel Downpipe.
Your factory downpipe is heavy, restrictive, and makes the turbocharger work a little harder to push that power through the limited piping. COBB solves this issue by designing a 3" downpipe with smooth bends that allow the exhaust gasses to escape more efficiently. Additionally, this downpipe features the provisions for your factory 02 sensors but also comes with an extra provision to install an aftermarket wideband if needed. COBB implements a custom spun metal substrate high flow catalytic converter which has been designed from a one-piece 400-grade stainless steel which has a better flow rate and longer life when compared to the factory unit. Once installed, this downpipe will definitely provide more power, better torque, and reduce turbo lag as well.
The Cat-Back Exhaust System has been fabricated from 304 Stainless Steel and works well with the downpipe. This exhaust system has been designed with smooth mandrel bends that reduce turbulence under acceleration and provides an aggressive exhaust note that really exposes that flagship flat 4 rumble. Exhaust hangers were welded onto the stock locations which means that you don't have to make any further modifications when installing this exhaust system. The exhaust gasses will exit through quad 3.5" Double Wall Tips.
Once installed, you will see improvements in both horsepower and torque, with reduced turbo lag and improved throttle response. You will also have an aggressive exhaust note under idle, as well as under acceleration. Additionally, this exhaust system will be ready to run the COBB OTS Tuning Maps.
Note: A new Turbo to Downpipe and Donut gaskets are not included and recommended.
