Removing the DPF, CAT, SCR, and DOC also removes emission sensors, so the ECU needs a DPF delete capable tune to run. Without a tune the truck sets codes and can go into limp mode.

The pipe is made from T-409 ferritic stainless steel, which is magnetic, unlike the commonly assumed non magnetic T304. You can verify the material with a magnet. At 2mm wall thickness it resists corrosion better than aluminized steel and costs less than T304, making it the best value exhaust metal.\"\n      }\n    },\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Should I choose a 4 inch or 5 inch delete pipe?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"A 4 inch pipe keeps more low end torque and gives extra clearance from the frame and rear axle, which suits daily driving and towing with a lightly or moderately tuned truck. A 5 inch pipe flows more at high rpm but can lose a little low end response.
