will this allow me to go from a 3" downpipe to 4" exhaust?
View Staff Answer 
The SILVERLINE DCK1 3.5"-4" ADAPTER KIT is a universal adapter designed to slip over a 3.5” piece of exhaust pipe and transition to a 4” piece of exhaust pipe (which it will also slip over). This part is universal and does not have any specific application information.
