Description

The MagnaFlow Performance Exhaust Diesel Turbo Downpipe 15398 is a 3in. diameter mandrel bent stainless steel pipe designed to connect near your turbocharger and is weight-optimized with superior flow characteristics and performance. Each performance pipe is produced using precision CNC robotic manufacturing techniques and features 100% durable, corrosion resistant stainless steel construction. Professional installation is highly recommended.

Product Overview

MagnaFlow Y-Pipe and Tru-X Pipe transitions are great for single/dual, dual/dual and balance tube applications. MagnaFlow's stainless steel Tru-X crossover pipe represents a significant leap forward in technology over traditional H-pipes. The more gentle radius allows for better exhaust gas scavenging, noise cancellation and better balance between cylinder banks. The result is a significant increase in power and torque but a reduction in db sound levels... the best of both worlds.
