FREE !!!!!  4" V-CLAMPS !!!!!

100% SUS-304 Stainless Steel and CNC Machine Flanges For Strong Solid Support. All of our welds are TIG welded and will not come apart. All Inlet tubes are bead Rolled, and All Exhaust Connections are V-Band Connections. The downpipe has a 3" v-band flange to bolt onto any stadard T4 turbo that has a 3" v-band exhaust housing. This includes all the popular Precision 61, 63, 66, 67, 71, 74 mm model turbos. The downpipe necks out from a 3" flange to a full 4" diameter in a very short distance. You don't need to purchase two v-band clamps to install this setup. Beware, a full 4" turboback exhaust is VERY VERY loud. The downpipe includes bungs for a wideband and O2 sensors.
