Anyone have a set after up grading?...want any prospective 4200 to sound a little more sporty. Or will a H or X pipe give the same effect?

By themselves the X/H pipes won't make much difference.......need the boxes/straight throughs

Safrane, wouldnt GS back boxes on a 4200 need the valves activating? In normal mode, I'd expect them to be only marginally different in sound.....though I may be wrong!
