Relentless Automotive Development High Flow Downpipes

For the 2025+ Ram 1500 Hurricane Standard Output (SO)

Unlock the true potential of your Hurricane Standard Output engine with the Relentless Automotive Development High Flow Downpipes.

Designed specifically for the 2025+ Ram 1500 equipped with the 3.0L Hurricane SO engine, these downpipes eliminate the restrictions found in the factory exhaust while maintaining OEM fitment and installation points. Every set is engineered to increase exhaust flow, reduce backpressure, improve turbo efficiency, and deliver a deeper, more aggressive exhaust note without compromising drivability.

Each downpipe is handcrafted in the USA from premium 304 stainless steel using precision TIG welding with full back purging to ensure maximum weld strength, corrosion resistance, and long-term durability.
