Flow for Catbacks
Stock 0HP
Loudmouth 12HP
corsa 8HP
borla 8HP
hooker 8HP
Flowmaster 5HP
I have a Crapmaster 80 series muffler and would like to switch over to the Hooker catback. Is it a more free-flowing than the flowmaster 80? In other-words, should I switch? I dont want a loudmouth on my 'vert with longtubes and no cats so I'll sacrifice a few ponies there.
