Product Details

The Gibson 5537 Cat-Back Dual Split Exhaust System is engineered to deliver an aggressive exhaust tone, reduced backpressure, and measurable performance gains. Built from mandrel-bent, heavy-duty aluminized steel tubing, this bolt-on cat-back system is a direct replacement for the factory exhaust with no cutting or welding required. Dual tips exit straight out the back, and the system is compatible with most factory bumpers, roll pans, and trailer hitches.

Performance:

  • Dyno-proven gains of 10–15 horsepower and 15–20 lb-ft of torque, optimized in the 1,800–3,000 RPM range
  • Reduces exhaust backpressure for improved engine efficiency
  • Gibson Superflow baffled and chambered muffler design produces a deep, aggressive sound with minimal interior drone
  • Approximately 5–8 decibels louder than stock

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
