i mean like, i havent heard borla in person, ive heard the magnapack setup in person, sounds great. the whole mac setup with the pro chamber(doesnt matter what brand long tubes imo unless you get shit), sounds great too. i mean i think in the future im gonna go with a borla catback with other things, right now i just have a flowmaster super 40 catback and im putting in a summit o/r h, and this will hold me up until i have enough money to really get what i want lol
