Product Details

The Gibson 616611 Cat-Back Single Exhaust System is a bolt-on performance exhaust upgrade engineered for maximum low-end power delivery. Dyno-tested to produce 10–15 horsepower gains and 15–20 lb-ft of additional torque in the 1,800–3,000 RPM range, this system is purpose-built for drivers who demand stronger acceleration, improved hill climbing, and enhanced towing and passing capability.

The exhaust exits behind the rear tire, keeping cabin noise to a minimum while still delivering an aggressive exhaust tone. No welding is required — the complete system uses a straightforward, bolt-on installation for professional results at home or in the shop. Backed by a Lifetime Limited Warranty.

Muffler Details:

  • Baffled and chambered muffler design
  • No internal packing — eliminates burnout over time
  • Minimal interior drone for a quieter in-cab experience
  • Aggressive exterior exhaust note
  • Oval body dimensions: 8 in. x 11 in. x 24 in.
  • Inlet: 3.50 in. offset | Outlet: 3.50 in. offset

Tip Details:

  • 4 in. polished T304 stainless steel round tip with rolled edge
  • Clamp-on installation
  • Inlet: 3.50 in. | Outlet: 4 in. | Length: 12 in.

Constructed from corrosion-resistant T304 stainless steel, the Gibson 616611 is built for long-term durability and a polished, show-quality appearance right out of the box.

Customer service and ease of order placement with Autoplicity.com was everything is should have been. I had a question and my call was promptly answered and I was given great customer service not to mention their great pricing!

good seller

I received my parts when I needed them by and they were quality parts.

Great Price, Check out was easy with amazon, no hidden Charges. Will do business here again

Good seller. Prompt email on ordering information. Fast shipping.

nice online quick shopping and best Price

Excellent prices and fast shipping. Recommended. Saved $200 on an exhaust system compared to a major discount auto retailer. Cheapest prices I found online by far. It took a couple of days to process my order, which may have been due to the manufacturer,

Better prices and even better service. Will do business with again.

great

thanks

Autoplicity had the best price for my Thule 867 roof rack cargo bag. It was easy to pay thru my Amazon accont and the order shipped within 24 hours of my placing the order.
