i had and still have on my teg a magnaflow high flow cat, 2.5 all the way into a spoon style muffler loud as shit but wasnt too bad by far the loudest on the freeway and when you smashed the gas if your looking for something with a decent tone try going 2.25 into a magnaflow ss i have one of the canisters and my protege doesnt sound ricey at all has a nice tone on loud on the freeway super quiet at idle
