Product Details

The Gibson 65009 Dual Extreme Cat-Back Exhaust System is engineered for performance-driven truck owners who demand more power, a more aggressive sound, and a bolder look. This dual bolt-on cat-back system routes exhaust exits behind each rear tire at an aggressive angle, delivering a deep, powerful exhaust tone alongside dyno-tuned performance gains averaging 15–20 horsepower.

Constructed from stainless mandrel-bent tubing with a 2.50-inch diameter, this system maximizes exhaust flow while resisting corrosion for long-term durability. The baffled and chambered muffler design produces an aggressive exhaust note with minimal interior drone — no internal packing required. Each system ships complete with two polished T304 stainless steel round slash-cut tips that clamp on for a clean, custom appearance.

Key Features:

  • Dyno-tuned and tested for average gains of 15–20 horsepower
  • 2.50-in. stainless mandrel-bent tubing for improved exhaust flow
  • Baffled and chambered muffler — 8 in. round, 3.00 in. dual inlet, 2.50 in. dual outlet, 24 in. length
  • Aggressive exhaust tone with minimal interior drone; no internal packing
  • Dual exits behind each rear tire for an aggressive stance
  • Includes two 3.50-in. polished T304 stainless round slash-cut tips (inlet 2.50 in., outlet 3.50 in., 12 in. length)
  • No welding required — complete bolt-on installation using factory hangers and clamps
  • Made in the USA
  • Backed by a Gibson Lifetime Limited Warranty

The Gibson 65009 is sold as a complete kit including all necessary hardware for installation. UPC: 677418007725.

I like that your site has the quantity available for each item. I just tried to order this same item from another site which eventually canceled the order because the product was not in stock and they were unable to attain more from the manufacturer.

Great Price and questions were answered by a real person on the phone, who had specific knowledge of this product, unlike a local dealer! Thanks!

Everything was easy to find and very easy to order.

Quick and easy!
