1.) The Bassani exhaust system arrives in a box that looks like this, open box and pull out axle back exhaust. The package should consist of a pair of axle back exhaust, 2 clamps, 2 inlet slip adaptors, 1 anti-seize compound and instruction sheet. 

2.) Use wrench or 15mm socket wrench to connect inlet slip adaptors to one end of the exhaust and secure using the clamps that arrived with the package. 

3.) Do not over tighten clamps as you may need to adjust the inlet slip adaptors for alignment once underneath the vehicle. 

4.) Lift and support vehicle with floor jack. Locate the connection between mid-pipe and factory mufflers found close to differential. The spot weld tab must be cut or broken in order to loosen factory ball and socket clamps. It is a very small tab weld and is easily breakable. I personally used a hammer and a flat head screw drivers to pry the weld lose. Make sure not to damage the factory clamps in the process as they will be reused for installation of the Bassani exhaust. 

5.) Once weld is broken, 14 mm socket to loosen factory ball and socket clamp. Detach factory mufflers. Spray rubber hangers with WD40, this will help the hooks on the factory muffler slide off easier. Once the factory muffler is completely removed, make sure to keep the factory clamps remaining on the mid pipe outlet. 

6.) Get Bassani exhaust, and slide into place. Make sure to slide all 3 hooks to the rubber hangers on the car. Connect Bassani exhaust inlet slip adaptor to the mid-pipe outlet of vehicle. Secure it in place by sliding factory clamps over connection. Align exhaust tips with rear lower valance of vehicle. Once properly aligned, use 14mm socket wrench to securely tighten factory clamps. 

7.) Once both exhausts are evenly aligned, safely lower vehicle. Start engine and listen to exhaust. Exhaust note must be even from both outlets. 

8.) After first 50-100 miles of driving with new exhaust, recheck exhaust condition and retighten clamps underneath vehicle.
