Will be replacing my standard old 3 box exhaust system on my mk2 gti. Considering a 2 box stainless 57mm Powerflow system with the option of a resonator if it's too loud. Would this system be preferential over a standard stainless freeflow system from a local exhaust dealer? Running a 2L bottom end on k-jet with a Powerflow branch. What's the pros / cons of the setup options? Thanx
