Product Details

The Gibson Performance 315511 is a cat-back single side exhaust system built for trucks and SUVs that demand more low-end muscle. Constructed from 3-inch aluminized mandrel-bent tubing, this bolt-on system is engineered to reduce backpressure, improve exhaust scavenging, and deliver measurable gains in both torque and horsepower — all while keeping interior cabin noise to a minimum.

Dyno-tested to produce maximum power gains in the 1,800–3,000 RPM range, this system is ideally suited for towing, hill climbing, acceleration, and everyday performance driving. Average gains of 10–15 horsepower and 15–20 lb-ft of torque make this one of Gibson's most capable single exhaust offerings. The system exits behind the rear tire for a clean, factory-plus appearance.

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!

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

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

very good, for my first time .
