i have magnaflow resonator and exhaust... no drone, just nice deep tone in certain revs. at WOT going by at 130, it sounds like demonic.
i wouldn't spend the money on SS straight pipe; any good shop should be able to bend a 2.75 pipe for you for A LOT LESS.
magnaflows range from $110 to $130 depending on tip. i highly recommend magnaflow as it doesn't drone due to how it's built... no chambers or something like that.
