Gibson 65587 Dual Extreme Cat-Back Exhaust — 2015–2022 Chevrolet Colorado / GMC Canyon 2.5L & 3.6L

The Gibson 65587 Dual Extreme Cat-Back Exhaust is the definitive bolt-on performance upgrade for 2015–2022 Chevrolet Colorado and 2015–2022 GMC Canyon owners running the 2.5L four-cylinder or 3.6L V6. Built from 409 stainless steel with mandrel-bent tubing, the dual extreme system exits behind each rear tire and caps off with a pair of massive 4-inch polished stainless tips for an aggressive look that backs up its sound. Whether you daily-drive, tow, or tackle trails in your Colorado or Canyon, the 65587 delivers dyno-proven power gains with all hardware included ships same or next business day from Black Ops Auto Works.

Why the Gibson 65587 Outperforms Stock

The factory exhaust on the 2015–2022 Colorado and Canyon is a compromise built for cost, not performance. Gibson replaced that restriction with a 3-inch mandrel-bent 409 stainless headpipe flowing into 2.25-inch mandrel-bent tailpipes a larger, smoother bore that reduces backpressure from the manifold exit all the way to the tip. The result: dyno-proven average gains of 10–15 HP and 15–20 lb-ft of torque, peaking in the 1,800–3,000 RPM range where daily driving and towing actually live.

The Gibson Superflow muffler uses a baffled-and-chambered design with no internal packing so sound stays consistent and drone stays minimal, but the exhaust note deepens noticeably under load. No packing means no degradation over time. What you hear at installation is what you hear at 100,000 miles.

Gibson 65587 vs. 65586 vs. 65585 — What's the Difference?

The 65587 is the maximum-aggression option — symmetric dual exits behind each rear tire, the widest visual stance, and the most balanced exhaust note of the three. Choose 65587 for dual-side exits behind the tires. Choose 65586 if you want dual tips exiting straight out the back center. Choose 65585 for a clean single-exit look.

Installation Notes

• True bolt-on — all factory mounting hangers used, all clamps and hardware included. No welding, no fabrication.
• Works with most factory rear bumpers without modification.
• Short bed trucks only: Crew Cab Short Bed configurations require cutting the headpipe 12.5 inches. Single straight cut pipe cutter or reciprocating saw, takes about 5 minutes. Long bed configurations require no cutting.
• Typical install time: 1–2 hours with basic hand tools.
• No ECU tune required. No check engine light on a properly functioning OEM catalytic converter and O2 sensors.

Note: Exhaust sound is louder under towing conditions due to increased engine load this is normal and expected.
