Using this exhaust is a breeze. First, gather all the necessary tools and make sure your vehicle is parked on a flat surface. The exhaust comes with V - Band clamps and flanges for an easy installation. Just match it up with the factory mounting points on your 20 - 23 Toyota GR Supra 3.0L Turbo 6cyl and secure it in place. No cutting or drilling required! When you're driving, enjoy the enhanced performance and the great exhaust tone. As for maintenance, it's a good idea to check the clamps and connections regularly for any signs of looseness. You can also clean the exhaust tips from time to time to keep them looking good. If you notice any strange noises or performance issues, have a mechanic take a look right away.
