Let's get this slant turbo project started. 71 Dart

i went 2.25" with my j pipe. it works well. if i were to make another one i would probably use 2" just for that slightly faster spool. also using the remflex 2.25" exhaust gasket. its nice. ive had the j pipe off a couple times and it is still good. same with the head to manifold gasket. nice crush on it and it seals beautifully. i would recommend any of the remflex gaskets. have had nothing but good experience with them.
