            Review from Kooks 3 in. Green Catted Y-Pipe (14-18 6.2L Silverado 1500 w/ Long Tube Headers)


            Y-Pipe was very nice and easy to install from the kooks headers to the Magnaflow exhaust system. Even with the green cats the truck still threw a check engine light which I expected.
