Anyone used Summit Racing SUM-680121 2 1\2 dual exhaust kit on a 68-72 442 with the dual exhaust bumper and trumpets? Wondered how the tail pipes fit? Do they hang too low? Does it exit in the right spot on the bumper for the tips? Seems like a decent kit for the price, also made in the USA. Has pretty good reviews. May install this kit on my 71 442 (455 with Thorley headers) with the Pypes 2 1\2 trumpets. Thanks in advance. https://www.summitracing.com/parts/sum-680121/overview/
