Great buy! Sounds terrific under acceleration, but nice and quiet otherwise. Perfect for my gs 430!

Easy installation even from a novice standpoint! Sounds great and definitly helped torque and gas mpg. Can't say exactly how much concerning the mpg due to also adding superchip, but combined I am saving 4-5 mpg easy in the city/highway. Great investment!!!
