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

Gibson is known for making well-built exhaust systems that improve performance. This particular cat-back system is designed for your 2006-2011 Chevrolet HHR LS with the 2.2L engine. It's built to give you better acceleration, more power for climbing hills, and increased towing and passing capability. While it's a performance exhaust, Gibson focused on keeping the sound comfortable inside the cab, making it quieter than other performance options. You can expect to see an average increase of 10-15 horsepower and 15-20 lb-ft of torque, with the biggest gains showing up in the low-end RPM range, from 1800 to 3000 RPM. This makes a noticeable difference when you're starting from a stop or need extra grunt.

The system uses 2.5-inch mandrel-bent stainless steel tubing for smooth exhaust flow, which is key to getting those performance gains. It features a Superflow™ CFT muffler that's baffled and chambered, designed to reduce interior drone while still giving an aggressive sound outside the vehicle. The exhaust exits behind the rear tire with a polished stainless steel, round, slash-cut tip for a clean look. Installation is straightforward thanks to the bolt-on design, which uses factory-style hangers and includes all the necessary hardware, meaning no welding is required. This makes for a hassle-free installation process with a professional finish.

This Gibson exhaust system comes with a Lifetime Limited Warranty, reflecting the durability of the stainless steel construction. If you're looking to get more out of your HHR's engine, especially for everyday driving, towing, or just wanting a bit more responsiveness, this system is a solid choice.
