Product Details

The Gibson 315519 is a cat-back single side exhaust system constructed with aluminized mandrel-bent tubing, engineered to deliver meaningful performance gains in real-world driving conditions. Dyno-tested for peak output in the low-end power band, this system is an excellent upgrade for trucks that see regular towing, hauling, or hill climbing duty.

The swept-side routing exits cleanly behind the rear tire, keeping the install looking factory-clean while reducing interior drone compared to other performance exhaust systems. The baffled and chambered muffler design requires no internal packing, producing an aggressive exterior tone while maintaining a quieter in-cab experience.

Performance Specifications:

  • Average horsepower gain: 10–15 HP
  • Average torque gain: 15–20 lb-ft
  • Peak power gains at 1,800–3,000 RPM
  • 3-inch aluminized mandrel-bent tubing throughout
  • Exit position: behind the rear tire

Muffler Details:

  • Design: Baffled and chambered — no internal packing
  • Sound profile: Aggressive exterior tone with minimal interior drone
  • Shape: 8-inch round body
  • Inlet: 3.00-inch offset; Outlet: 3.00-inch offset

Exhaust Tip Details:

  • Material: Polished T304 stainless steel
  • Style: Round slash-cut, clamp-on
  • Inlet: 3 inches; Outlet: 3.5 inches

Backed by Gibson's Lifetime Limited Warranty, the 315519 is a proven bolt-on performance exhaust built for trucks that demand more low-end grunt and a commanding exhaust note.

Easy to use, quick check out, and decent prices

Item prices are good, shipping cost just needs to be lower

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Offered me a 30% discount on shipping.

Great pricing and quick shipping. I'll be using them again for sure.
