Product Details

The Gibson 5573 Cat-Back Dual Split Exhaust System delivers an aggressive, throaty exhaust note and improved engine performance for truck and SUV enthusiasts.

Gibson exhaust systems are engineered to decrease exhaust backpressure, resulting in improved torque and increased horsepower. Typical dyno-tested gains average 15–20 horsepower. The dual split rear exit configuration works with most factory bumpers, roll pans, and trailer hitches, and note that exhaust tone increases under towing and load conditions.

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 !

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