Your HHR gives you a driving experience like no other. Upgrade to a Chevrolet HHR performance muffler to get the most out of it by improving airflow while keeping your vehicle as quiet as possible. Performance mufflers are engineered to make the best use of acoustic materials that give you the most out of your muffler.

Upgrading when you already need a new HHR muffler helps you get the most value out of your vehicle by replacing your old muffler with a new design that works to enhance your engine's airflow. This delivers a small performance bump that makes a big difference in some engines, and new muffler designs bring you a quieter driving experience in the vehicle you already love.
