aFe DPF, DEF & CAT Delete Exhaust Systems

aFe's Premium Delete Exhaust Systems replace the entire exhaust from the downpipe back with 5" straight pipe. They do not require welding or modification and install easily using OEM mounts and hanger locations. Exhausts from aFe are precision engineered and manufactured in Corona, CA using high quality steel and welds. Featuring smoother bends and premium hardware, these exhausts were built for the roughest of conditions and are designed to outlast and out-perform the competition.

  • The Steel: Premium Quality, 5" Aluminized or Stainless Steel Tubing
  • The Engineering: aFe uses precision engineering and mandrel bending to create smoother turns in their pipes resulting in greater flow than the competition.
  • Benefits: Greater exhaust flow results in better HP and torque while reducing EGTs and eliminating "Regen" resulting in a truck that is both, more powerful and more efficient.
  • Simple & Secure Installation: aFe's precise engineering and premium mounting hardware ensures that your exhaust installs easily using OEM mounts and hanger locations without cuts or welds. Once installed, it will stay in place.
  • Options: Free flowing 24" mufflers are paired with their exhausts, while the stainless models generally offer your choice of a polished or black high temp powder-coated stainless steel tip.

CMRP EGR Delete Kit

EGR Delete Kits from CMRP are constructed of Stainless Steel and Machined Billet Aluminum at an incredibly affordable price. The kit allows for the removal of the EGR Coolers and blocking/deleting the EGR Valve.

  • Craftsmanship: Each kit from CMRP is Made in the USA from quality Billet Aluminum and Stainless Steel.
  • What's Included: 1 Block Plate, 2 Bypass Hoses and Hardware
  • Benefits: Lower EGTs, Increased Low-End Power, Reduced "Black Smoke" Emissions
