1970 Duster AlterKtion, 4 Link, LS/T56/Turbo and Minitub

I believe your 8-3/4 has as much space / room as the 9" (of the purple Dart above) with the Lynx mounts identical. The difference I notice between the TTi system and AbodyJoes pic is the TTi systems mufflers had offset outlets.

pics of only mods (took out about 4" per side) to the TTi 3" package with Street Lynx. amazing how symmetrical the tail pipes and the whole system for that matter is
