Using this exhaust system is a breeze. First, make sure your car is parked on a flat surface and the engine is cool. Then, simply remove the factory muffler system and bolt on our new exhaust kit. There's no need to make any modifications. You can choose between a polished or a burnt stainless - steel tip according to your preference. As for maintenance, regularly check the bolts to make sure they're tight. Clean the exhaust tip with a mild cleaner to keep it looking good. If you notice any unusual noises or performance issues, have it checked by a professional. Also, remember that removing the factory muffler may change the sound of your car, so make sure you're okay with the new noise level.
