This exhaust is so loud and deep with the valves open that I’m actually scared to install my downpipe. I love the option to close the valves on command which solves the issue in AU where the stock valves and other exhausts retaining the stock valves remain always open no matter in sports mode or comfort mode. It even allows you to hear some small pops and burbles in comfort mode. Aesthetics 10/10. Recommend having it installed professionally for hardwiring and managing one area with tight clearance. Delivery was faster than I expected considering from the US. Thanks to Sequential Racing for delivering to my door on a Saturday (Melb based) too
