    Amazing

    Amazing quality and instead of 2-4 weeks shipping, the folks at Corsa were able to get me my system in 3 days! Easy to install, sounds great and very happy with the sound! Absolutely ZERO drone in any gear, at any RPM and even in cylinder deactivation. I couldn’t be happier! Thank you Corsa for making this system for what seems to be a rare 157”WB setup with out factory dual exhaust!
