Product Details

The Gibson 66549 Dual Split Cat-Back Exhaust System delivers a powerful combination of performance gains, aggressive exhaust tone, and premium stainless steel construction. Engineered for maximum low-end output in the 1,800–3,000 RPM range, this bolt-on system is a direct replacement for the factory exhaust with zero cutting or welding required.

Performance Gains:

  • Dyno-proven gains of 10–15 horsepower and 15–20 lb-ft of torque
  • Reduces backpressure for improved throttle response and acceleration
  • Optimized for low-end power delivery — ideal for towing, hill climbing, and passing

Gibson Superflow Muffler:

  • Baffled and chambered design with no internal packing
  • Produces a deep, aggressive exhaust note with minimal interior drone
  • 7 in. round body; 3 in. center inlet; 2.50 in. dual outlet; 24 in. length

Tips & Tubing:

  • 3.50 in. polished T304 stainless steel round slash-cut tips — clamp-on design
  • Tip specs: 2.50 in. inlet; 3.50 in. outlet; 12 in. length
  • 2.50 in. 409 stainless mandrel-bent tubing for maximum flow and durability
  • Dual tip exit straight out the back

Installation & Construction:

  • 100% bolt-on installation — no welding required
  • Includes all hardware and factory-style hangers for a seamless fit
  • Compatible with most bumpers, roll pans, and trailer hitches
  • Proudly Made in the USA
  • Backed by a Lifetime Limited Warranty

They had an item that was somewhat hard to find at a reasonable price. Glad I found them.

Excellent shopping experience so far. It was easy to find what I need, and I didn't have to buy more than I need.

Absolutely the best bargain you'll find! Don't pay retail mark up at the parts store, buy at Autoplicity and know you're saving money.<br>.

Easy website to shop on. Good phone support. Package will be arriving in a timely manner. All in all seems like a good company.
