Using your MBRP Armor Pro exhaust is easy. First, make sure your vehicle is parked on a flat surface and the engine is cool. Then, follow the included installation instructions to bolt on the exhaust. Once installed, start your car and enjoy the improved power and the moderate exhaust note. When it comes to maintenance, regularly check the bolts to make sure they're tight. If you live in an area with snow and salt, it's a good idea to wash the exhaust every few months to prevent corrosion. Keep an eye on the carbon fiber tip cover for any signs of damage. And always remember, this exhaust comes with a lifetime manufacturer warranty, so if you have any issues, reach out to the manufacturer.
