Product Description

This is a custom manufactured mandrel bent exhaust Y Pipe for the Ford Superduty’s & E-Series with a 5.4L V8 and 6.8L V10. Ford’s factory y pipe is formed and does not direct the exhaust and harmonic vibrations out which restricts the exhaust flow, forcing you to lose HP, torque and gas efficiency. The SPD’s collector utilizes the pulse vacuum that is generated. 

Pulse Vacuum – By grouping primary exhaust tubes into a collector, the vacuum pulse from one cylinder can be used to create a vacuum on the other exhaust ports. This vacuum will cause the exhaust to begin flowing more quickly as the exhaust valve opens. The collector must be long enough and small enough to keep the inertia of the exhaust pulse optimized while keeping back-pressure low.

Some of its benefits are:

  • Its function is to free up the factory restricted exhaust connection, giving you more horsepower, torque, and gas efficiency. Our Y Pipe has two 2.5″ mandrel bent pipes transitioning to 3”. The factory Y Pipe downsizes to 1.5” inch pipes which restricts the exhaust flow, forcing you to lose HP, torque and gas efficiency.
  • The dyno tests we performed show a gain of 33HP and 35 torque. This test was performed on a F-250 crew cab.
  • You will get an extra 1-2 mpg.
  • It is very easy to install. Just cut the old Y Pipe out and weld the new performance Y Pipe in. It comes with a coupler for easy install.

Other Information: Due to legalese, I have to state that “this product is for off-road use only.” This product has not been approved by the state emissions department, however, it will not cause your vehicle to fail a smog test. Please check your Excursion/F250/F350 to make sure it has the restrictors. Somewhere during the 2000 year, Ford changed the exhaust design (there are two different exhaust versions for the year 2000, “old style” and “new style”). Ford installed the restriction points as an attempt to silence the exhaust flutter issue. Our y-pipe was specially designed and tested as a more efficient fix for the problem. Other Y’s may not have the same results.
