Installing Exhaust System

Always check the installation dimensions (danger of noise, component collisions)! 

1. Push new exhaust clamps (clamping sleeves) onto the exhaust pipes. The threaded joint must be pointing downwards.
2. If you have not already done so, position the exhaust system on a transmission jack and secure it using a tension strap. -arrows-
