Product Details

The Gibson 8100 Cat-Back Dual Extreme Exhaust System delivers aggressive dual-exit performance for truck enthusiasts who demand bold looks and real power gains. Constructed from hot-dipped aluminized steel with 2.50-inch mandrel-bent tubing, this system is dyno-tuned and tested to reduce exhaust backpressure and deliver average gains of 15–20 horsepower. Both outlets exit behind the rear tires at an aggressive angle for a purposeful, high-performance stance.

Key Features:

  • 2.50-in. Aluminized Mandrel-Bent Tubing — Smooth, consistent exhaust flow through every bend for maximum efficiency
  • Baffled & Chambered Muffler Design — 8-in. round body with 2.50-in. dual inlet and 3-in. offset outlet (24-in. length); no internal packing for minimal interior drone with an aggressive tone
  • 3.50-in. Polished T304 Stainless Steel Slash-Cut Tips — Round slash-cut clamp-on tips; inlet 2.50-in., outlet 3.50-in., 12-in. length
  • Dual Rear Exit — Both pipes exit behind each rear tire for a performance truck aesthetic
  • True Bolt-On Installation — Includes all hardware and factory-style hangers; no welding required
  • Dyno-Tested Performance — Engineered and tested for measurable horsepower and torque improvements
  • Made in the USA — Proudly manufactured domestically
  • Lifetime Limited Warranty — Backed by Gibson's industry-leading warranty coverage

Gibson Performance Exhaust is a leading manufacturer of aftermarket performance exhaust systems for trucks, SUVs, and off-road vehicles. Every system is custom-engineered for a precise, hassle-free bolt-on fit with professional-quality results straight out of the box.

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

Good customer service.Very friendly persons in service dept as well. Will shop here again.

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!
