their cat back is basically a muffler back..
it has a nice rumble @ idle and has a nice deep tho not excessive rumble under load, not much sound at all cruising the highway (that i can hear anyway...the cars around me who knows
i'll be having a shop add the Y down the road, hopefully it'll add a little more oomph
a true cat back woulda been nice but meh, what ya gonna do
everything in the 16869 is clamp so install is pretty easy, hardest thing we ran into is lining up the tips center to the bumper...i'll try a little a/o and a bar when i get some time
