Product Details

The Gibson 615604 is a cat-back single side exhaust system built for maximum low-end performance. Featuring a swept-side exit behind the passenger rear tire, this system is engineered for truck owners who demand real gains in acceleration, towing capacity, hill climbing, and passing power — all while keeping interior cabin noise to a minimum.

At the heart of this system is a baffled and chambered Superflow muffler with no internal packing, delivering a deep, aggressive exhaust tone outside while maintaining minimal interior drone. Dyno testing confirms peak torque and horsepower gains occur in the critical 1,800–3,000 RPM range, with average increases of 10–15 horsepower and 15–20 lb-ft of torque.

Quick and easy, just how I like it! Would definitely recommend Autoplicity. Steve Douglas

Great will buy from again *+++++

Quick shipping and the battery terminal connectors that I ordered have a better look and quality than I expected. Thank you for a great deal.

It was quick. And the part was accurate

Very easy process:)

Easy as pie

Wish the delivery was a couple days sooner

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

The best price on what I was looking for and fairly fast to get it shipped out considering it was drop shipped directly from the manufacturer. Autoplicity has a huge selection and I will definitely be back when ever I need other automotive parts.

The best prices and fast shipping!

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>.

great service, even better price! Would recommend Autoplicity to anyone.
