What is the primary benefit of a titanium cat-back exhaust?

The primary benefits are a significant reduction in weight compared to stock or stainless steel systems, and improved exhaust flow due to the 3-inch diameter piping. This can lead to better engine performance and a more aggressive exhaust sound.

Does this exhaust system require any modifications to my catalytic converter?

This is a cat-back system, meaning it replaces the exhaust components from the catalytic converter back. It is designed to bolt up to the factory catalytic converter outlet, so no modifications to the converter itself are typically needed for installation.

Will this exhaust system cause drone inside the cabin?

COBB designs their mufflers to produce an aggressive sound while minimizing unwanted drone at cruising speeds. While exhaust notes can be subjective and vary with driving conditions, this system is tuned for a balance of sound and comfort.

Product Details

This is the COBB 3-inch Titanium Cat-Back Exhaust system specifically for the 2011-2014 Subaru WRX Hatchback and the 2008-2014 Subaru STi Hatchback. A cat-back exhaust replaces the factory system from the catalytic converter back, and this COBB system is built to offer a more aggressive sound and improved exhaust flow compared to stock. It’s a significant upgrade for enthusiasts looking to enhance their vehicle's performance and auditory experience.

Constructed from high-grade titanium, this cat-back system is notably lighter than a comparable stainless steel or factory exhaust. Titanium is chosen for its strength-to-weight ratio and its ability to withstand high temperatures, contributing to both performance and durability. The 3-inch diameter piping is designed to reduce backpressure, allowing your engine to breathe more freely. This can lead to a more responsive throttle and a noticeable increase in power, especially when paired with other engine modifications. The system includes COBB's signature muffler design, tuned to produce a deep, resonant exhaust note that is aggressive without being overly raspy or droney at cruising speeds. All necessary hardware for installation is included, making it a complete package for your upgrade.

When installing a cat-back exhaust, you can expect a more pronounced exhaust note that will be more apparent inside the cabin, particularly during acceleration. The titanium construction also means this system will develop a unique patina over time as it heats and cools, giving it a distinct look. This COBB cat-back exhaust is a well-built component designed to integrate seamlessly with your Subaru's existing exhaust layout from the catalytic converter back.
