ADDING NPP BACK IN ???
So… In search for more volume… I went ARH + HFC + AWE Touring…
Amazing IDLE… but WOT was terrible… so I added a 3rd X pipe muffler… now WOT is great but low speed it quite… thinking of adding back in the NPP valves in a custom location before the AWE just for the moments when I want more idle volume… has anyone used the 2.5” NPP valves as a cut out and dump valve?
Any issues you can think of?
