Product Details

The Gibson Exhaust 312700 Cat-Back Dual Split Exhaust System delivers an aggressive throaty sound and bold appearance for enthusiasts seeking maximum performance and style. This complete cat-back system reduces backpressure to produce measurable gains in torque and horsepower, with typical increases averaging 15-20 horsepower over stock exhaust systems.

Key Features:

  • Dual split design with polished stainless steel tips exiting straight out the back
  • Baffled and chambered muffler design with no internal packing for long-lasting performance
  • Minimal interior drone for comfortable highway driving
  • Compatible with most aftermarket bumpers, roll pans, and trailer hitches
  • Bolt-on installation with no welding required
  • Aluminized steel construction for corrosion resistance
  • Backed by Gibson's Lifetime Limited Warranty

Specifications:

  • Muffler: 7-inch round body, 24 inches long with 2.50-inch center inlet and dual 2.50-inch outlets
  • Tips: 3.5-inch polished T304 stainless steel, round slash-cut design with clamp-on installation
  • Tip dimensions: 2.50-inch inlet, 3.50-inch outlet, 6.5 inches long

This exhaust system produces a more aggressive exhaust note that becomes louder under acceleration and towing conditions, delivering the performance sound enthusiasts demand without excessive cabin drone during normal driving.

Product was exactly what I ordered. Good transaction

great price, quick shipping!

easy ordering, great prices

Good overall expierence

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.

The Best Pricing online period! The shipping was very reasonable with great communication and tracking number proviced. My parts were boxed well and arrived right on schedule. This was my first purchase with Autoplicity but will for sure not be my last.
