dual exhaust for our trucks

[pedrofixlater]

I recently bought a dual exhaust kit for my 75 stepper from Dynomax. I paid 115.00 They have various kits for headers non headers 4x4 or 2wd. Thr reason i am putting this in is I got the 89007 kit for a 2wd 73-82 truck. When I put on the pipes one side went in great, the other side had a header pipe miss marked so I called dynomax and they are next day airing me the correct pipe. Note: All the kits i have seen from them are 2 1/4 inch pipes. I know some people have been looking for dual pipe kits.
