Product Details

The Gibson Exhaust 615584 Cat-Back Single Exhaust System delivers exceptional performance gains for trucks and SUVs demanding improved acceleration, towing capacity, and passing power. This stainless steel exhaust system is engineered to maximize low-end torque and horsepower where it matters most—between 1800 and 3000 RPM. Dyno-tested results demonstrate average gains of 10-15 horsepower and 15-20 lb-ft of torque, making this Gibson's best-performing exhaust system for drivers who need real-world power improvements.

Key Features:

  • Single side exit configuration positioned behind the rear tire
  • Baffled and chambered muffler design with no internal packing for durability
  • Minimal interior drone with aggressive exhaust note
  • Round muffler: 8-inch diameter, 24-inch length with 3-inch offset inlet and outlet
  • 4-inch polished T304 stainless steel round slash-cut tip (clamp-on style)
  • Tip dimensions: 3-inch inlet, 4-inch outlet, 12-inch length
  • Bolt-on installation with no welding required
  • Quieter in-cab experience compared to other performance exhaust systems
  • Backed by Gibson's Lifetime Limited Warranty

This complete cat-back system includes all necessary hardware for a hassle-free installation with professional-grade results. The T304 stainless steel construction ensures long-lasting corrosion resistance and maintains its polished appearance for years of reliable service.

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

Good prices compared to other websites. Good customer reviews. Pretty fast shipping. I would recommend this site.

Great prices and quick shipping! I will be back!!

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>.

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