Product Details

The Gibson 65641 Cat-Back Dual Split Exhaust System is a bolt-on performance upgrade engineered to deliver increased power, an aggressive exhaust tone, and a polished look. Constructed from mandrel-bent 409 stainless steel tubing, this system is built for long-term durability while maximizing exhaust flow from the catalytic converter back.

Performance Gains:

  • Reduces exhaust backpressure for improved engine efficiency
  • Dyno-proven to add 10–15 horsepower and 15–20 lb-ft of torque
  • Power gains concentrated in the 1,800–3,000 RPM range for real-world drivability

Gibson Superflow Muffler:

  • Baffled and chambered internal design — no internal packing
  • Deep, aggressive exhaust note with minimal interior cabin drone
  • Muffler dimensions: 8 in. round body; 3 in. offset inlet; 2.25 in. dual outlet; 24 in. length

Exhaust Tips:

  • 3.5 in. polished T304 stainless steel round slash-cut tips
  • Clamp-on design for easy fitment
  • Tip specs: 2.25 in. inlet; 3.50 in. outlet; 12 in. length
  • Dual tips exit straight out the rear for a clean, factory-plus appearance

Installation & Compatibility:

  • Hassle-free bolt-on installation — no welding required
  • Uses factory hangers and clamps for a clean, professional fit
  • Compatible with most factory bumpers, roll pans, and trailer hitches
  • Note: Exhaust sound may increase under towing conditions

Proudly made in the USA and backed by Gibson's Lifetime Limited Warranty, the 65641 is a complete cat-back system ready to install right out of the box.

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!

I was very pleased with my transaction with Autoplicity. My order was shipped the next day and received the following day. The pricing was also the best I could find. I would definitely buy from them again and recommend them to others.

very prompt service,items were in stock and shipped next day,salesman was helpful and friendly.Will place in favorites and do buisness with again.

Lowest prices, free and fast shipping, excellent product.

Great shopping experience - best price & shipping I could find!
