Switch to npp

I currently have a full borla set up with headers straight piped to borla s type mufflers. If I want to switch to npp mufflers do I need anything other than the mufflers piping wise? Or can I do a simple muffler swap with my current piping? Not sure If I want it open all the time or vacuum actuators, would that change things?

Open npp with headers is loud AF. I tied the valves shut... sounds nice

I know a guy that had an ls2 vette and he had full exhaust with the npp setup for the vacuum actuators, sounded badass lol

Love my NPP, you should look up online the components of the NPP but in reality a set of just nice flow masters or borla etc are more inline with what most would do rather than dual mode which you would have to engineer to make the flaps open and close....theres posts on that also. Or if your too loud some Monza tips may help or cut outs.... The vacuum system is not used on the next gen just electric for the bypass in the mufflers....and its not a easy thing to install just the system as its vacuum on ours with little tanks that connect etc etc...

I build a vac controller for mine. great when its early or i have a headache. I ca build another if you want one. It basically programs to the garage buttons and lets it open or close. minimal power draw too ( left it on overnight lol )
