Product Details

The Gibson 65632 Cat-Back Dual Extreme Exhaust System delivers aggressive dual-exit performance with a bold street presence. Built with 3-inch 409 stainless mandrel-bent tubing, this system is dyno-tuned and tested for real-world performance gains, with average increases of 15–20 horsepower. The dual exits are positioned behind each rear tire at an aggressive angle, combining an attention-grabbing appearance with a powerful exhaust note.

At the heart of the system is Gibson's baffled and chambered muffler design — engineered for minimal interior drone while delivering an aggressive exterior sound. The system is finished with polished T304 stainless steel slash-cut tips for a clean, high-performance look.

They had an item that was somewhat hard to find at a reasonable price. Glad I found them.

paypal hard to use

The best prices and fast shipping!

Shopped for the best price I could find on my combo pintle/tow hitch and Autoplicity came in the lowest. So I'm expecting maybe a super long delivery right? Nope they shipped it Immediately and I just got it like 3 days later. I will order again in a heartbeat. Have no fear their a great supplier

great service, even better price! Would recommend Autoplicity to anyone.

Easy website to shop on. Good phone support. Package will be arriving in a timely manner. All in all seems like a good company.
