Product Details

The Gibson 5639 Cat-Back Super Truck Exhaust System delivers a loud, deep, and powerful exhaust note through dual tailpipes that exit in front of the rear tires, finished with a polished stainless steel tip. Designed as a true bolt-on upgrade with no welding required, this system is engineered to improve acceleration while delivering measurable power gains on the dyno.

Typical dyno-tested results average 10–15 HP and 15–20 lb-ft of torque over stock. The aggressive race-rumble tone is tuned through a baffled and chambered muffler design with no internal packing material, keeping interior drone to a minimum while maintaining an assertive exterior sound. Backed by Gibson's Lifetime Limited Warranty.

  • Design: Baffled and chambered, no internal packing
  • Sound character: Aggressive, minimal interior drone
  • Body: 4 x 9 x 18 in. oval

Just ordered so I’m not sure yet. Free shipping is why I left 4 stars. Once I receive my item I will update my review.

Thank u

Good

After shopping around at my local auto parts stores and not liking what they had in stock I decided to go on line and BANG found Autoplicity.com and they had just exactly the black finished lug nuts that I was looking to give my Trailblazer SS a different look with the stock wheels, 5 ⭐️ 's and definitely will recommend them, thanks again Autoplicity.

Easy to place order!

Everything great

It was simple and fast I would have to say I'll be back in the future to get more parts

it was aiight

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!

so far so good

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.

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.
