Description 655Z-32T D&D 2-into-1 Diablo Gato Chrome for 2017-2025 Harley FLH/FLT Touring Models Check out our video on the Diablo Gato “Devil Cat” D&D Exhaust System. This is on our 2014 Street Glide. D&D 655Z 32T Diablo Gato 2-into-1 Exhaust for 2017 & Newer Harley-Davidson Touring The D&D 655Z 32T Diablo Gato 2-into-1 exhaust transforms your Milwaukee-Eight Touring bike with stronger torque, quicker throttle response, and an aggressive performance tone. Unlike stock systems, this 2-into-1 design maximizes exhaust scavenging and increases velocity through the stepped header. As a result, your bike accelerates harder and pulls stronger throughout the RPM range. In other words, you don’t just hear the difference — you feel it. Because D&D engineered this system specifically for 2017 & newer Harley-Davidson Touring models, it supports everything from stock 107 and 114 setups to serious big-inch performance builds. Whether you’re adding a cam, tuner, or full motor work, the Diablo Gato provides the flow capacity your build demands. Performance Benefits Increased low-end and mid-range torque Sharper throttle response Deep, aggressive performance tone Strong support for cam and tuning upgrades Optimized flow for Milwaukee-Eight engines Most importantly, this exhaust delivers usable power — not just noise. So when you roll on the throttle, the bike responds immediately and pulls with authority. Fitment Fits 2017 & newer Harley-Davidson Touring models, including: Street Glide Road Glide Road King Electra Glide Other FLH and FLT Milwaukee-Eight Touring platforms Why Riders Choose the Diablo Gato Many riders want sound. However, performance riders want results. That’s exactly why the D&D Diablo Gato stands out. It combines aggressive styling with proven dyno gains. At the same time, it maintains rideability and strong low-end torque — which matters on a heavy Touring chassis. So if you’re serious about building a performance bagger, this system helps you make your Hawg fly.
