Pro Shoot Out 4000 Series

The Pro Shoot Out is just what it sounds like, the purest of the pure racing muffler

This muffler is for all out racing where sound requirements are very liberal. This unique patented muffler is compact and light weight, yet still very effective.  Reduced outlet increases torque and reduces DBs.

Case size varies...16 ga. aluminized steel or 304 SS at additional cost

Designed for vehicles driven for racing events where decibel levels are 100 - 105 DBS
