Silverline 6.0L Powerstroke 409 4" Stainless Off Road Exhaust System




Complete Turbo Back Exhaust System with Stainless Welded Hangers

Silverline™ direct-fit exhaust systems are engineered to improve your vehicle’s overall performance by generating more horsepower and torque. Using precise measurements, the mandrel bent tubing and increased pipe diameter ensure optimum exhaust flow for all of our vehicle-specific systems.

Our diesel kits reduce exhaust gas temperatures and improve gas mileage, while independent dyno tests confirm performance improvements by as much as 13 horsepower and 23 ft. lbs. of torque.  Sport compact systems also register dyno-confirmed horsepower gains yet still bolt to factory emission systems.

The systems are designed to install on standard, Super and Crew Cab trucks with both short and long beds.

The 6.0 Liter down pipe is three and one-half inches in diameter to make installation and performance with the 6.0 liter engines VRT turbo perfect.
The down pipe then joins with the four-inch stainless steel tubing just before the transmission cross member. Joining the two pipes just before the cross member eliminates the need to remove the cross member for installation.
The four-inch section joins with the spiral flow core straight-through muffler just before the rear axle.
The spiral flow louvered muffler is specifically designed for diesel performance. The muffler dampens the diesel exhaust resonance and keeps the interior sound level within 3dB of stock, while allowing a healthy sounding exhaust outside the cab.

There is an optional converter test pipe available for the 6.0 liter trucks.

The XP409 stainless steel systems are protected by a 5 year warranty, to the original purchaser.

Average gains with this system are 18hp and 40 lb-ft of torque, as well as decreased turbocharger spool up times and exhaust gas temperatures.
