Product Details

The Gibson Exhaust 315634 Cat-Back Single Exhaust System delivers exceptional performance gains for trucks and SUVs requiring improved acceleration, towing capacity, and passing power. This aluminized steel exhaust system is engineered to maximize low-end torque and horsepower where it matters most—between 1800 to 3000 RPM. Dyno-tested results show average gains of 10-15 horsepower and 15-20 lb-ft of torque, making this Gibson's best-performing single-side exhaust configuration.

  • Single side exit design behind rear tire for optimal flow
  • Baffled and chambered muffler design with no internal packing
  • Aggressive exhaust note with minimal interior drone
  • Quieter in-cab experience compared to other performance exhausts
  • Low-end power optimized for towing and hill climbing

Muffler Specifications:

  • Oval body dimensions: 4 inches x 9 inches x 18 inches
  • 3-inch center inlet with 3-inch offset outlet
  • Durable chambered construction requires no maintenance

Exhaust Tip:

  • 4-inch polished T304 stainless steel round slash-cut tip
  • Clamp-on installation for easy fitment
  • 12-inch length with 3-inch inlet and 4-inch outlet

very easy and fast purchase but concerned as fedex requires no signature for delivery and is not careful to which house yard it leaves packages in the front of ,so far anyway.

fast shipping and great communication my order was shipped the same day thanks autoplicity

I was looking for a hitch mount bike rack for our bicycles. After doing a little looking around locally I found the exact rack I wanted at Autoplicity at a huge discount. It also shipped quickly, and I appreciate that.<br><br>Thanks!

it was great

Best price super fast shipping and an easy transaction. will definitely buy from Autoplicity again.

Great pricing, but did take a while to ship. I believe this was due to the product being on backorder from the manufacturer.

Great prices very fast shipping!!!

thanks

Error occurred after I submitted my order the first time.

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984
