Product Details

The Gibson 615623 Filter-Back Single Exhaust System is a performance diesel exhaust upgrade built for serious power and deep, aggressive sound. Engineered for improved acceleration, hill-climbing ability, towing capacity, and passing performance, this system delivers real, dyno-proven results you can feel.

Performance Gains:

  • Dyno-proven gains of 10–15 horsepower and 15–20 lb-ft of torque at low RPM (1,800–3,000 RPM)
  • Reduces exhaust gas temperatures for improved engine efficiency under load
  • Quieter inside the cab than competing performance exhaust systems
  • Deep, commanding exhaust tone outside the vehicle

Construction & Components:

  • 4-inch mandrel-bent 409 stainless steel tubing for unrestricted flow and long-term durability
  • 6-inch polished T304 stainless steel round tip — weld-on design (4.00 in. inlet / 6.00 in. outlet)
  • Gibson Superflow muffler with baffled and chambered design — no internal packing, nothing to blow out
  • Minimal interior drone with an aggressive exterior sound profile
  • Exits behind the rear tire for a clean, factory-integrated appearance

Installation & Warranty:

  • Complete bolt-on, no-weld installation — includes all hardware and factory-style zinc-plated hangers
  • Professional fit and finish with no fabrication required
  • Made in the USA
  • Backed by a Lifetime Limited Warranty

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.

Fast shipping great customer service!

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.

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.
