Product Details

The Gibson 65642 Cat-Back Dual Extreme Exhaust System is built for truck and SUV owners who demand serious performance, an aggressive exhaust note, and a bold street presence. Exits are positioned behind each rear tire at an aggressive angle, delivering a commanding look to match the powerful sound.

Performance:

  • Dyno-proven gains of 10–15 horsepower and 15–20 lb-ft of torque, optimized for peak output in the 1,800–3,000 RPM range
  • Reduced backpressure through mandrel-bent tubing for unrestricted exhaust flow
  • Improved throttle response and low-end power delivery

Construction:

  • 2.25-in. 409 stainless steel mandrel-bent tubing for long-lasting durability
  • Gibson SuperFlow™ Muffler with baffled and chambered design — no internal packing, minimal interior drone, aggressive sound character
  • Muffler specs: 8 in. round body; 3 in. offset inlet; 2.25 in. dual outlet; 24 in. length

Tips:

  • 3.5 in. polished T304 stainless steel round slash-cut tips — clamp-on style
  • Tip specs: 2.25 in. inlet; 3.50 in. outlet; 12 in. length

Installation & Warranty:

  • Bolt-on installation — no welding required
  • Zinc-plated 3/8 in. to 1/2 in. hangers and clamps included
  • Proudly Made in the USA
  • Backed by Gibson's Lifetime Limited Warranty

Very quick easy transaction. Recommend to anyone looking for auto accessories.

Best price on the internet. A lot cheaper than amazon, so I was pretty surprised.

easy

Autoplicity was very helpfull in finding the right part for my vehical. I got my order in 2 days and all was in good shape. They had the best price by several dollars on my part. I will be doing business with them in the future.

No issues at this time with transaction.

Thanks for having a BETTER price than even the manufacturer on the chip I bought!

Well, I'll start with saying this...I wanted a specific product from COBB tuning that they sell. It was priced lower than any other company so I bought it. This happened on the 22nd, I ended up calling them almost a week later to request tracking info. They were very friendly when they notified me it wouldn't be able to ship out till the 3rd of feb. For a 2 lb item I thought this was pretty slow. They apologized for COBB holding the order up. Its now the 7th, should get my item today!! Overall its a good company with friendly employees, Shipping time is lacking but a trade off for the lowest price. I would refer a friend for price and also mention shipping time expectations. I do believe there's something to be said for quality customer service and low prices...It's becoming harder and harder to find companies that posses such qualities. Honestly, if they had a faster shipping method I would give them a perfect rating.<br>

** Update 4/18/2012<br>Everything arrived in several different shipments. I did experience a problem with some FelPro Headbolts that I had ordered. I ordered two and only received one, but after a short phone call with Paul from shipping, the problem was fixed and my second set of bolts were shipped.<br><br>They had the cheapest price that I could find on several products. I did not like the order confirmations on there website as I had to copy and paste to search for my tracking number. I am supposed to receive my order today and I am scared because the two weights do not match up. Autoplicity says 37.7 pounds and fedex says 3.8 pounds. Maybe there is more than one tracking number and I just do not know.

Excellent price on name brand items, best prices for Bosch oxygen sensors.
