Product Details

The Gibson Performance 618804 is a single side exit cat-back exhaust system constructed from high-quality stainless steel, engineered to maximize low-end power where you need it most. Dyno-tested to deliver peak torque and horsepower gains in the 1800–3000 RPM range, this system is purpose-built for improved acceleration, hill climbing, towing, and passing performance. The side exit design routes exhaust behind the rear tire, contributing to a noticeably quieter in-cab experience compared to other performance exhaust systems.

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

Great price on at least my item. A bit high on the two day shipping. Hopefully the shipping is quick!

The best prices and fast shipping!

Lowest price for the part, 1/2 the shipping of others. Ordered Monday nite here on Thursday. The right part. Things are good.

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.

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