Product Details

The Gibson 5659 Super Truck Cat-Back Exhaust System is a performance-engineered, bolt-on exhaust upgrade designed to unleash a deep, aggressive race-inspired tone and deliver measurable power gains. Built with aluminized mandrel-bent tubing (3-in. primary / 2.0-in. dual outlet), this system flows exhaust efficiently from the catalytic converter back, replacing the restrictive factory exhaust with a free-flowing design.

At the heart of this system is Gibson's signature baffled and chambered muffler — featuring a 4 x 9 x 18-in. oval body with a 3.0-in. center inlet and dual 2.0-in. outlets. The chambered design eliminates internal packing for a bold, powerful exhaust note while keeping interior drone to a minimum. Dual tailpipes exit in front of the rear tires and are capped with 6-in. polished T304 stainless steel rectangular tips for a clean, aggressive finish.

Key Features:

  • Dyno-tested power gains averaging 15–18 horsepower and 15–20 lb-ft of torque
  • Deep, aggressive race-rumble exhaust tone with minimal interior drone
  • Dual tailpipe exits positioned in front of the rear tires
  • 3-in. / 2.0-in. aluminized mandrel-bent tubing for maximum flow
  • Baffled and chambered muffler — no internal packing
  • 6-in. polished T304 stainless steel rectangular tip included
  • Includes all hardware and factory-style hangers for a direct bolt-on fit
  • No cutting or welding required
  • Backed by a Lifetime Limited Warranty

Important Notes: This system is not recommended for towing applications. Noise level may exceed the 95-decibel standard. UPC: 677418026726.

So far so good, great price.

Great smooth transaction. Tracking number provided. Would not hesitate using them again.

quick check out

Great.

Checked everywhere - lowest price on the web.

Best pricing I could find anywhere on the Hawk Brake Pads, ordered on a Sunday, had them by Wednesday Outstanding!<br>

Had a great first experience with Autoplicity. I ordered my package late in the day on Wednesday and it was at the front door Thursday! Another big plus is that their prices are hard to beat. Won't have a problem ordering from them again!

prices are good. After I paid it took them 5 days to ship the order. Communication is not very good with autoplicity.

Cheapest parts anywhere! Fast and reasonable shipping. Great products - never any issues!

so far so good

easy buying. great prices
