The boost activated cutouts that we use are available online, we do not have them on our site, since each installation has been a custom setup for that particular installation.
I don't need a ton of horsepower If I gain a hundred that will be more than enough for me. I would like 2.5 but I just don't care for the pipes going up the back of the sling and don't like the option coming out of the back side exhaust exit either. Really like the Thermal r&d but that's just 2". Would the 2" be better than stock with the supercharger?
wokka and Dave@DDMWorks answered your question. My two cents is go with the 2”. Make sure you have the cat delete and get the supercharger.
