Where does the DPF&CAT Pipe go?
The DPF/CAT delete pipe isn't a full exhaust system, it only replaces the section of your factory exhaust that contains the emissions parts, specifically the "CAT" and the DPF (Diesel Particulate Filter). Those are the two barrel shaped parts in your exhaust near the middle of your truck.
The front end of the delete pipe connects to your down-pipe and the tail end of the delete pipe connects to the tail pipe, just before the bend over the rear axle.
The delete pipe is the same diameter of your factory exhaust system, so it will be a perfect fit.
I have a muffler. Where do I install it?
If you purchased a muffler to compliment your DPF&CAT pipe, you have two suggested locations to place the muffler!
A. MOST RECOMMENDED
B. SECOND MOST RECOMMENDED.
Depending on your truck bed, you may need to cut your pipe to modify your pipe length for fitment. Please make sure to measure twice before cutting!
You can really place the muffler anywhere along the system as long as it makes sense to you. These are our suggestions only.
