i have the 427 with 1 3/4 inch ceramic coated headers, then the super 40's from flowmaster. im thinking of just changing out the mufflers. What mufflers flow really well and keep hp up while still sounding really good?

i have PS LT's, 3" ORY and a flowmaster catback, its extremely raspy , very loud to loud for me. they flow bad suposedly as people say even tho ive never seen flow numbers but im gonna be switching to HOOKER, the magnaflow doesnt sound much diffrent than flowmaster IMHO hearing videos on ls1 sounds just a little less raspy. maybe with cats it would sound better but im goin with hooker and i think ill be very happy with that
lots of people say the flowmasters do suck. but i heard that 1 chamber muflfler, and all i can say is that it sounds sickkkkkk.... hey awhile back, i saw somewhere where a guy dynoed all his mods and when he put on magnaflow he lost 10rwhp
