This header has exceeded my expectations in terms of PERFORMANCE and sound. As a hesitant automotive enthusiast, i was not sure if this product was worth the investment. But as a result of my tests I determined that it has significantly improved my ride .The increased horsepower and torque make driving a joy, and the aggressive exhaust note turns heads on the road. The only con is that it can be a bit pricey for those on a tight budget, but the quality justifies the cost..
