Product Details

The Gibson 615571 is a cat-back single exhaust system engineered for maximum low-end performance. Constructed from stainless steel with 3-inch mandrel-bent tubing, this swept-side system exits behind the rear tire and delivers a deep, aggressive exhaust tone while keeping interior cab noise to a minimum.

Dyno-tested results demonstrate peak torque and horsepower gains in the low-end power band between 1,800 and 3,000 RPM, with average gains of 10–15 horsepower and 15–20 lb-ft of torque — making it an ideal upgrade for towing, hill climbing, acceleration, and passing power.

Key Features:

  • Stainless steel, 3-inch mandrel-bent tubing for unrestricted exhaust flow
  • Swept-side exit position — exits behind the rear tire
  • Minimal interior drone for a quieter in-cab experience
  • No welding required — complete bolt-on installation with all hardware and factory-style hangers included
  • Backed by a Lifetime Limited Warranty

Muffler Specifications:

  • Design: Baffled and chambered, no internal packing
  • Sound: Aggressive tone with minimal interior drone
  • Body: 8 in. round
  • Inlet: 3.00 in. center
  • Outlet: 3.00 in. center
  • Length: 24 in.

Exhaust Tip Specifications:

  • Style: Round slash-cut, clamp-on
  • Material: Polished T304 stainless steel
  • Inlet: 3 in.

A service

Order for Borla exhaust filled quickly, correctly and shipped safely. Previously I had to cancel an order for the same item at a competitor who gave nothing but excuses for non-shipment of item. And at a higher price! Autoplicity had best price, service, and followthru on purchase. Will be a returning customer without a doubt.

super service and best price on the net

Best prices and easy manipulation of website

I selected 2nd day delivery as I need this ASAP. please and thanks

Went to ebay, amazon, and summit racing looking for this part and finally found it here after looking on this site for about 10 seconds.

I will see when I get my exhaust how it was
