and i keep seeing threads with different info. im getting confused.
i have a 2002 ss camaro 35th anny. it has what i believe to be stock ss exhaust. it has only 2 tips and they are seperated (not the boxy ones under the license plate).
i found a thread with the stock muffler serial number listed but i cant find it again. mine looks like this
several numbers
4
then several numbers.
now my question is, on my muffler, what are my inlet and outlet sizes? i tried to eyeball it on a tape measure and inlet looked like 2.5 and outlet 2.75 inches, but i was at a weird angle so those may be off a lot.
also i have read that my I pipe is 2 3/4 inches then i read 3 inches. is it correct that only the dual/dual has a 3 inch i pipe?
i'm wanting to do a muffler only for now (not catback) and then after i save up for headers and y pipe i will do a cutout.
thanks for any help in advance. please know that i did search and search but people posting contradictory info just confused me more.

so like on the magnaflow muffler there is no 2.75 inlet. do i get a 3 inch or 2.5 inch inlet? also will the muffler shop be able to weld them in with no extra fittings?

i agree that short term a cutout would be great bang for my buck, but i am mostly looking for good sound until i can save up for headers/y/cutout. i dont know if my thinking is dumb here or not. let me know if im being a thick-skulled noob.

another quick question: as far as a cutout and muffler inlet, do i go with 3 inch or 2.5 inch on a stock i pipe? and does the shop have to "make them work" or what?
