stepside exhaust trouble
« on: February 04, 2010, 08:58:16 AM »
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?

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.
