Whipple discharge tube porting service for 96-00 GMC/Chevy. Includes removal of the restrictive discharge exit and wall smoothing. Requires customer manifold to be sent in.
Please note that there is an extra fee for disassembly and assembly when not combined with a rebuild. We cannot guarantee the condition of any consumable components with supercharger porting services. Remember, this is port work, not a rebuild. If you wish to have it rebuilt, please choose this service when the item is sent in, so that it can be handled by the correct department. See rebuild section on rebuild pricing and information.
