Thanks for purchasing Stainless Works Muscleflow 3” Exhaust System for your SRT8/

Old Exhaust System Removal
1. Let car cool completely and allow exhaust to cool completely to the touch before
starting any work.
2. Disconnect battery.
3. Raise and support vehicle.
4. Remove (2) 13mm bolts holding left rear tailpipe on and remove from rubber
hangers, then remove pipe.
5. Loosen 2 clamps at front of the X-pipe and the remaining hangers on system.
This may require some force to separate at clamped area.

Exhaust System Installation

over factory or header lead pipes (Use the 2-3/4” adapters and clamps for an
