mid pipe question...but this one is different than the rest
 

ok i live in md so i have to have cats on my mid pipe
so if i have to have cats which is better
a h-pipe with cats or a x pipe with cats
does it still stay the same as w/o cats like does the h-pipe still sound better and the x-pipe still have a bit more hp?

sorry i know thei topic has been talked about alot but i searched and a couldnt find anyone talking about the mid pipe with cats
