Issue Exhaust is not fitting correctly
Wrong or missing parts

Solution
Most fitment issues are due to improperly adjusted exhaust. This includes tip fitments and rattling due to chassis contact. Check out our fitment guide for more installation tips.
Double check the parts list for your system and compare them with what you received. Fill out our contact form, found below and let us know what parts you need.

Once installed properly, your AWE exhaust will provide years of trouble-free performance.
The exhaust volume and sound will settle with usage; 800-1000 miles is required to break-in new exhaust systems.
Also, please note that the rear 180Technology® resonator has a small drain hole to allow condensation to escape. Water drops from this area are normal.
Periodic cleaning of exhaust tips is necessary to maintain proper finish, especially in areas prone to road salt and caustic deicing solutions. Use a mild soap and water solution or car wax to clean the finish. Avoid using abrasive polishes, as they can scratch the finish.
