I just started to put full length hedmann headers on my 81 c10 stepside and after getting both headers in with ease i realize that the tranny cross member is only about 3ins away from the end of my header and once i put my reducer on it hits the crossmember making it impossible to hook up my exhaust what can i do?
-
My buddy had the same problem and he ended up heating the headers with torches and bending them out of the way. It's crude but it worked.
-
How low is your truck? DO you have pix? You can modify or move the crossmember or buy a dual exhaust crossmember. What trans do you have?
-
My truck is stock height it has a turbo 350 trans, sorry i can't get pics for you
-
if i heat them up wont the pipes want to kink them i'm out a set of headers
-
nvm guys i just cut the collector off and took out 4 inches which gain me enough room to put in an z looking bend lol but im pretty dang proud of myself!

ino this is a little old but, i just put the exhaust back on my 84 stepside. the crossmember is closer to the cab floor on the pass side of the truck and i had to do some dumb stuff with the pipes. i have the flowtech cheap headers on and they are angled down a little and not straight parralel to the floor, i bought the s bend pieces of pipe from headman that come off the collector and over the trans member. i ended up just running a straight piece of pipe under the crossmember cutting an angle to bring the end of pipe connecting to the reducer,up towards the bottom of the crossmember and using the s bend to raise up enuough to tuck the muffler (super 44s) up under the bed. worked alright

I used those S-extensions and they worked perfect for my truck. My crossmember was also clearanced by the previous owner when he installed some headers off a newer model truck....so I don't know if that affected the clearance issues or not.
