Ok so I just got the two magnaflow high flows put in with all four cats removed, and I have a flowmaster cat back.(not happy with it) Anyone else with the high flows which cat back are you using ?
I used to have Bassani headers, Bassani mid-pipe and Bassani catback. Now I have Kooks longtubes, JDM mid pipes and Bassani catback but switching to the JDM Silverbullet catback.
If I were you I would go with the Silverbullet through JDM. It is basically Magnaflow and over the years I have heard it is the loudest/meanest catback out for our trucks.
