Product Details

The Gibson 5642 Cat-Back Dual Extreme Exhaust System is a bolt-on dual-exit performance exhaust built for truck and SUV owners who want aggressive sound, real power gains, and a bold street presence. The system exits behind each rear tire at an assertive angle, delivering a deep, aggressive exhaust tone tuned to complement daily driving with minimal interior drone.

Engineered with 2.25-inch aluminized mandrel-bent tubing, this system reduces backpressure and improves exhaust flow for dyno-proven performance gains. The baffled and chambered muffler design produces a powerful exhaust note without the unwanted cabin resonance common in less-refined systems.

Key Features:

  • Tubing: 2.25 in. aluminized mandrel-bent tubing for improved flow and durability
  • Muffler Design: Baffled and chambered; no internal packing; minimal interior drone; aggressive sound profile
  • Muffler Dimensions: 8 in. round body; 3 in. offset inlet; 2.25 in. dual outlet; 24 in. length
  • Exhaust Tips: 3.5 in. polished T304 stainless steel round slash-cut tips — clamp-on style
  • Tip Dimensions: 2.25 in. inlet; 3.5 in. outlet; 12 in. length
  • Exit Position: Dual split rear — exits behind each rear tire
  • Includes all hardware and factory-style hangers for a clean, professional installation
  • No cutting or welding required — true bolt-on fitment
  • Made in the USA
  • Backed by a Lifetime Limited Warranty

The Gibson Dual Extreme delivers dyno-tuned street performance with an average gain of 15–20 horsepower, making it one of the most capable cat-back systems in the Dual Extreme lineup. The polished stainless slash-cut tips add a striking visual upgrade to complement the performance improvements under the hood.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Great prices, great selection

I was very pleased with my transaction with Autoplicity. My order was shipped the next day and received the following day. The pricing was also the best I could find. I would definitely buy from them again and recommend them to others.

Lowest prices, free and fast shipping, excellent product.

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.

Quick and painless
