Use my writeup as a guide. You can check your sizes against this and confirm if its stock or not.
The LSJ exhaust is not 2.75", not even 2.5", it starts off at just a bit over 2". I was running my turbo downpipe to this for sometime and it barely fit but did bolt up. I have since replaced my catback with a 3" system.
The downpipe bolts onto the stock 2 bolt flange but sadly the entire catback is restricted starting with the 2" opening into the resonator.
The exit to the resonator is 2.6"
Pipe after resonator is 2.49"
Pipe after resonator then shrinks down to 2.23" before entering the muffler
The muffler opening is 2.23"
The muffler exit is 2.49"
These are all OD dimensions meaning the actual ID of the pipe is even smaller..

search for exhaust clips on youtube...
You need to get rid of that restrictive cat, mid pipe, and stock resonator. Put in 1 piece of 2.5 to match up to the rear pipe, if you dont want rasp install a 2.5" resonator from a new high flow cat back to the stock 2.5 inch pipe. It will be all you need for your stock supercharger, even with mods. This can be done at a local exhuast shop for 100-200 bucks if they arent total rip offs.
