Gibson 06-09 Chevrolet HHR LS 2.2L 2.5in Cat-Back Single Exhaust - Aluminized

Starting with 2.5-inch aluminized steel tubing, this Gibson cat-back exhaust system is built for your 2006-2011 Chevrolet HHR. It's designed to exit behind the rear tire with a polished stainless steel slash-cut tip, giving your HHR a more aggressive look. The system uses a Superflow CFT muffler, which Gibson engineers to provide a notable increase in low-end torque and horsepower, especially between 1800 and 3000 RPM, making it easier to climb hills or pass other vehicles.

This exhaust is constructed with mandrel-bent tubing to ensure consistent pipe diameter throughout, which helps maintain exhaust flow. The muffler itself is baffled and chambered, a design choice that Gibson uses to create an aggressive sound outside the vehicle while minimizing interior drone. This means you get the performance benefits without the annoying cabin noise that often comes with aftermarket exhaust systems. The kit includes all the necessary hardware and factory-style hangers, making it a straightforward bolt-on installation that requires no welding.

With an average gain of 10-15 horsepower and 15-20 lb-ft of torque, you'll feel a difference in acceleration and power. Gibson backs this system with a Lifetime Limited Warranty, giving you confidence in its durability.
