Installation on 1970 El Camino

Summit RacingSummit Racing Verified Purchase

Items arrived in a large box, no damage & everything look great. I had to cut off the pipe as it connects to the headers and add the correct flange, plus it was too short anyway. The over the axle pipes were too long and had to be cut to keep the tailpipes in the correct position. Overall it looks and sounds great, nice low price too.
