Using this exhaust tip kit is easy. First, find a suitable place to work and make sure your car is parked safely. If you're replacing the tip on your COBB Titanium Cat - Back Exhaust, carefully remove the old tip. Then, slide the new tip onto the exhaust pipe using the 3 - inch slip - joint inlet and secure it with the included clamp. For a custom - made exhaust, simply attach the tip in the same way. When it comes to maintenance, regularly clean the tip with a mild soap and water solution to keep its brushed'matte' finish looking great. Avoid using abrasive cleaners as they might damage the surface or the laser - etched COBB logo. Also, check the clamp periodically to ensure it's tight and the tip is securely attached.
