New Magnaflow Cat
Lol...posted 1 second before me...Thats exactly what im looking for...a muffler with the 1 inlet and dual outlets...im not sure what size im looking for here though. 2.50 in/out?? does the pipe change in diametere for in/out?? what size oval muffler am i looking for?? etc..I have been looking for posts on buickforums about this topic but cannot locate any posts containing any information for this setup. Thats why i came here to ask the Pro'* 
From what i have seen i think i have a 3" inlet and a 2.5 outlet. Could anybody chime in?
