Key Features:

• 3-inch mandrel-bent construction for maximum flow efficiency
• Fully machined and TIG welded upper and lower flanges
• 304 stainless steel construction designed to handle high temperatures and stresses
• Includes woven titanium sleeve that effectively insulates heat, protecting the engine bay

• Three-bolt triangular flange design for 2015.5+ models
• 50 States emissions legal (CARB E.O. D-701-36)

This premium replacement downpipe was engineered to shorten turbo lag by maximizing exhaust flow, resulting in less back-pressure and more power and torque for heavy-duty applications. Compatible with LML trucks with a three-bolt flange at the connection to the exhaust pipe.
