so i've been itchin' to wrench on the car lately so i shopped around and found a set of quad exhausts that looked good. they are made by magnaflow, stock #16491, touring series performance exhaust. the sound is deeper but not so much louder. the car gained the most noise with my downpipe anyway and i like it for what it is. the polished tail pipes are massive at 4 in. a piece and really catch the eye. the install was easy and fitment is about 95% accurate (the hangers are off about 10mm). i also had to cut the valance on the passenger side, of course, but had to trim the driver's side as well.
