I currently have ZZP 3 inch downpipe and 2.5 inch borla catback (I believe the old PFYC one) and am wanting a little more volume and power from it. Wanting to get a 3 inch zzp catback with no resonator and Borla xr1 mufflers. What do you guys think of this set up? Would it change much in tone or volume in a good way? Power? Also im in California. Thanks!
