SHOTGUN T.R.EX.™:

Totally Regulated Exhaust Stop... COMPROMISING BETWEEN TOP-END PERFORMANCE AND LOW-END DRIVABILITY. Get The Most Radical Camshaft You Can Find ----- Get A Free Flowing Performance Exhaust ----- And Then Get The SHOTGUN T.R.EX

NO MORE EXHAUST REVERSION:
As engine speeds and load conditions change, so do pressure waves in the exhaust system. The SHOTGUN "reads" these pressure waves and continuously adjusts exhaust flow to always maintain a negative pressure wave in the exhaust system, at any rpm.

CONTROLLED BACK-PRESSURE:
Highly tuned engines, equipped with radical cams and free-flowing exhaust, from low-end performance caused by too little exhaust suffers back-pressure. This situation allows some of the incoming fuel/air charge to leave the cylinder with the exhaust. The SHOTGUN supplies just the right amount of back-pressure to assure that the incoming air/fuel charge stays in the cylinder, assuring maximum horsepower and torque.

THE RESULT:

• High rpm horsepower and much improved drivability at lower engine speeds
• Low and mid-range torque increase
• No top-end power loss
• Faster acceleration
• Much improved idling
• Cleaner combustion
• Increased fuel economy
  

T.R.E X. :
A continuously adjusting valve, installed in the exhaust system. Controls back-pressure and eliminates exhaust reversion for a mid-range performance gain. All stainless steel construction virtually eliminates maintenance.

T.R.EX. can be used on engines of any size and is an easy bolt-on installation.
U.S. Patent #4,609,068
