Not unless experienced race shop will do a complete and proper install of all parts, incl underbody tray, chamber, etc. Most aftermarket defusers are a dead weight vs providing any usable function and likely wil create more aero disturbance vs what a factory has produced using wind tunnels. My 2 cents anyway
