Product Details

The Gibson 65586 Cat-Back Dual Split Exhaust System delivers an aggressive, throaty exhaust note and a bold dual-tip look without cutting into your weekend. Engineered to reduce backpressure throughout the exhaust path, this system is designed to unlock additional torque and horsepower — with typical gains averaging 15–20 horsepower. The straight-out-the-back dual tip exit works with most factory bumpers, roll pans, and trailer hitches, making it a versatile upgrade for a wide range of builds.

Construction centers on a baffled and chambered muffler design with no internal packing material, keeping interior drone to a minimum while producing a distinctly aggressive exhaust tone. Under towing loads, exhaust sound increases noticeably — a welcome trait for performance-minded truck and SUV owners.

Key Features:

  • Performance Gains: Reduces backpressure for average gains of 15–20 horsepower and increased torque
  • Muffler Design: Baffled and chambered construction — no internal packing, minimal interior drone, aggressive sound character
  • Muffler Dimensions: 4 x 9 x 18 in. oval body; 3 in. center inlet; 3 in. offset outlet
  • Tip Style: 4 in. polished T304 stainless steel rolled slash-cut tip, clamp-on installation
  • Tip Specifications: 2.25 in. inlet / 4 in. outlet / 12 in. length
  • Material: T304 stainless steel construction throughout
  • Fitment Flexibility: Compatible with most bumpers, roll pans, and trailer hitches
  • Installation: Hassle-free bolt-on installation — no welding required
  • Warranty: Backed by Gibson's Lifetime Limited Warranty

The Gibson 65586 is a true bolt-on performance exhaust upgrade, combining polished T304 stainless steel durability with a deep, commanding exhaust note. Whether daily driving or towing, this cat-back system is built to perform and last.

Only place that had my part for a reasonable price and great shipping options

found what I wanted , right price . ran it through Amazon Lifes good

hope this is what I'm looking for

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Easy!

I couldn't believe the low price! Glad I found this website, I will definitely be a return costumer.

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
