WHY replace a perfectly good stock exhaust system on your diesel truck?
Cardinal rule #1: Diesels HATE backpressure! Diesel pickup owners who have researched performance upgrades to their trucks' exhaust know several things are true.

1.  Exhaust gas temperatures (EGT) will drop when a better flowing exhaust system is installed - this is a good thing especially when towing.

2.  A larger diameter down-pipe a/k/a Turbo Pipe will allow for greater flow volume, as will a straight-through low-backpressure muffler, & the rest of the pipes in the system as well.

3.  Better flow = more Horsepower, Torque, & FUEL MILEAGE!

NOTE: It is illegal to remove catalytic converters on vehicles so equipped. Consult a professional to determine options.

Great Sound and Performance at a Great Price!
