RAPID FLOW INSTALLATION
REMOVAL OF STOCk EXHAUST SYSTEM
In these steps you will remove the stock
exhaust system.
1.Use a sawzall to cut the exhaust directly behind
the muffler.
2. Cut the Straight Pipe in front of the muffler.
3. Cut the stock Down Pipe just after the bend.
4. Loosen the stock band clamp using a 7/16”
deep socket where the stock down pipe is
connected to the turbo. The stock band clamp
will be used later so don’t remove it, just loosen
it enough to remove the stock down pipe.
5. To make removing the Hangers an easier process
it is recommended that you use a silicone spray
lubricant to spray each of the rubber hangers
holding the stock exhaust.
6. Remove each piece of the stock exhaust system,
including the stock exhaust hangers.
