Supercharger & exhaust catback pipes

[NitrOmm]

this is an exhaust question as it relates to SC & boost/power.
Just bolted on a Magna charger MP112. I am running Pacesetter longtubes & off road Ypipe. This runs into my stock pipe ( which is pretty big )then a magnaflow muffler.
Am I risking loss of power by not expanding into a little bit larger pipe to the muffler ? Will that effect the boost ?

FYI: I have a slightly reduced pully (3.1") to give 7lbs. as it compensates for my heads cam & longtubes already.
Thanks

you will not loose boost due to exhaust with a supercharger. a supercharger uses the engine belt system to rotate a compression system to create pressurized air that is then forced into the combustion chambers. a supercharger its self in not effected by exhaust. if you still have the stock I pipe you might see a change in power if you are running it into a 3" magnaflow muffler, if not there will be no large gain in swapping out the I pipe, if you go to a larger pipe you might see 2-5 hp max.
