Looking to add power to your GM Duramax LML? Most look at the
exhaust, intake, and programmer for horsepower gains. The factory
turbo direct pipe is often overlooked. MBRP has addressed this
restrictive component of the factory exhaust with their new
turbo direct pipe replacement that mounts between the factory
turbo and exhaust system. Featuring 16-gauge mandrel bent tubing
for maximum flow & extremely durable high-temperature ceramic
coating, these downpipes deepen the sound of your diesel V8
while lowering exhaust gas temperature and quickening throttle
MBRP down pipe provides a smoother flow from the turbo resulting
in lower EGT’s and increased performance. The down pipe
is a relatively easy install due to the precision bends that
you’ve come to expect from MBRP.
