Selling a 321 stainless steel mbrp 3" cat-back exhaust for a fiesta ST, about 7000 miles on it. I had known these exhausts drone very badly at highway speeds so I welded in a vibrant resonator and a 1/4 wavelength resonator tuned for 3200 rpm (basically 32" of pipe that's capped at the end, focus RS kits are using these a lot). Works very well and tucks in behind bumper so it's completely up out of the way. Car allows tons of burble and pop and sounds great at WOT but right when you settle in at 75-85 mph where these kits drone it cuts the frequency peak right off. Comes with all clamps, reuse the standard metal layered gasket (mbrp fiber ones are crap)

$375 + shipping. Located in metro Detroit, MI and local pickup is preferred
