Alex has brought me his Golf R many times and when it came time to buy a new exhaust for it, it was a no brainer that he wanted the best protection for the tips. Many new cars today have direct fuel injection and while this is great for performance, it causes a mess on the intake valves and the exhaust tips. Having a lifetime permanent metal coating on these AWE Tuning tips will help them look like new for a very long time and will make them much easier to clean. Also, in case you are wondering, the metal coating is good up to 1,000º F!
