Flowmaster's new Force II S.O.R kit for 2006-08 Chevrolet HHR takes this cool vehicle to the next level of performance, throttle response, and sound. The main purpose of your vehicle's exhaust system is to remove the exhaust gases from your engine in an efficient and lawful manner.

The 60 Series Performance muffler is designed specifically to bring Flowmaster performance to smaller cars and trucks with small displacement 4 and 6 cylinder engines. All 60 Series mufflers feature Delta Flow technology for increased torque, horsepower and reduced interior resonance.

Best of all, the system follows the factory exhaust routing and uses all of the factory hanger mounting points for easy and perfect fitment. HHR owners will notice a considerable improvement in exhaust note with this system and low interior resonance. This system will not work with the SS model HHR vehicles.
