Product Details

The Gibson 66504 Cat-Back Dual Split Exhaust System delivers an aggressive, throaty exhaust note and improved engine performance for truck and SUV enthusiasts. Engineered to reduce backpressure, this system is designed to generate measurable gains in torque and horsepower, with typical improvements averaging 15–20 horsepower.

Constructed from polished T304 stainless steel, the dual tip exit routes straight out the back of the vehicle for a clean, factory-plus appearance. The system is compatible with most aftermarket bumpers, roll pans, and trailer hitches. Note that exhaust sound increases under towing conditions. Installation is a straightforward bolt-on process with no welding required.

Key Features:

  • Muffler Design: Baffled and chambered construction with no internal packing — minimizes interior drone while delivering an aggressive exhaust sound
  • Muffler Dimensions: 7 in. round body; 3 in. center inlet; 2.50 in. dual outlet; 24 in. overall length
  • Tip Description: 3.5 in. polished T304 stainless steel, round slash-cut style, clamp-on fitment
  • Tip Dimensions: 2.50 in. inlet; 3.50 in. outlet; 12 in. overall length
  • Bolt-on installation — no cutting or welding required
  • Compatible with most bumpers, roll pans, and trailer hitches
  • Backed by a Lifetime Limited Warranty

The Gibson 66504 is an excellent choice for drivers seeking a performance cat-back exhaust upgrade that combines a bold exhaust tone with real power gains and durable stainless steel construction.

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

Fast Shipping and the lowest price on the Husky Floor Liners. I searched all the internet and this place had the best price. Shipping was not free but it was still cheaper than anywhere else with free shipping at those sites.

The best prices and fast shipping!

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>.

great service, even better price! Would recommend Autoplicity to anyone.

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