Enhance performance with a 4 inch aluminized steel downpipe.
The Flowmaster Turbocharger Down Pipe is designed to replace the restrictive factory 3-1/2 inch turbo downpipe in 7.3L Powerstroke engines. Constructed from 4 inch mandrel-bent 16 gauge aluminized steel, this downpipe ensures unrestricted flow, which is essential for maximizing engine performance. The direct-fit design allows for easy installation, bolting onto the turbocharger flange with a V-Band connection. This downpipe not only improves power and torque but also enhances throttle response and overall fuel efficiency. With its robust construction, it effectively reduces heat build-up, making it a valuable addition for those looking to increase their engine's capabilities.
