I have the Motordyne full exhaust with art test pipes does anyone know if you can add the electronic valve control for a quiet mode like the Gt haus exhaust

Using a valve means you'd have to add converters and run a whole system from the manifold back, there isn't enough room and not a great How about this option for less noise quieter exhaust, sell the ART pipes and bolt on Fast Intention HFCs? You won't notice any difference in WHP and you'll enjoy the sweet sound! I've never been an ART pipe fan, ran them for a week with stinky exhaust and not a great sound.

I'm thinking of running PPE long tube headers and removing the ART test pipes and upgrading the cams but I want to run a bolt on supercharger but doing research first on what I want to do thanks for the input
