I purchased a cat-back system for a Toyota Matrix. It installed easily and was a perfect fit. The system has great sound and there is a noticeable improvement in performance and gas mileage. I would definitely purchase a Magnaflow system again. NOTE: if you purchase the OEM Magnaflow catalytic converter along with the cat-back system (for a Matrix) you will need a 2-3%X94 pipe to go between the two as each product was intended to bolt to the factory system.
