Not sure if this is the right place to ask this but anyway here goes. I know sweet nothing about back pressure and all that on exhaust systems, I have a 97 vs series 2 clubby, stock with the factory hsv twin system and the rear resonator has been removed, sounds awesome but i was wondering if this could effect the performance in any way?? thanks.
