Banks Power - Exhaust Brake (fits Stock exhaust) 01-04 Chevy - 55233

Banks Brake is designed and tested by engineers to provide strong, safe and sustained braking power. If your truck hauls loads and navigates hills, don t settle for less. Some designs bypass so much exhaust flow that they provide little or no additional braking. Others restrict exhaust flow when not in use, impeding driving performance. With its large housing and intelligently designed butterfly valve, Banks Brake provides superior braking power and allows for better engine breathing when not in use.
