The Boost Monkey I D Reinforced Temperature Downpipe is a complete waste of money.Based on our own experience, the product doesn't deliver its promised benefits, and the gasket poorly performs. The only pro is THAT it looks nice but that's about it. On the downside, it fails to fit properly, which causes leaks and makes your car sound terrible. If you're looking for a reliable downpipe, steer clear of Boost Monkey I D Reinforced Temperature Downpipe..
