Which Resonator to use???
im thinking of making my own mid pipe, i know its gonna make my flow better but what about the back presure? i see some resonators have these gills inside that sticks out alot, some resonators look like an inside of an apexi muffler ( no gills sticking out ) which is better for performance?
