Exhaust?

Can't remember Heddman's p/n since this was 17 years ago that I changed out the PO's blown engine. I was on a budget but didn't want any Asian import parts. Also went with a Carter AFB [pre-Edelbrock] and Weiand 8004 intake [pre-Holley buyout]. H-pipe and dual exhausts thru turbo mufflers exiting behind rear tires Still running.

Re: Exhaust?
I just replaced a set of hedman headers in my 70. They are for a C20/C30 but also cross over to a 350 conversion in a CJ-5 or 7. The collector is next to the frame so they are plenty high.

Re: Exhaust?
Hedman for sure if running a manual trans. In general they are a good value for the $.

Re: Exhaust?
Have you looked into SUMMIT-brand headers? I am running the ceramic coated ones in my '68 for four years now and no issues, around $250 I think. Just put the unpainted ones for $130 in my '69 work truck, you just have to paint them yourself. They fit great and sound good. I don't know who manufactures them but they are very solid.

Re: Exhaust?
I think the regular headman headers are about $130 a set. That is your best bet.

Re: Exhaust?
So my neighbor has a set of short tube headers for 75 bucks, will they fit on this truck?

Re: Exhaust?
Shorties are no better than stock manifolds... if you want real headers, get the long tubes. Headman Hedders are good headers for the money.
I'd rethink glasspacks dumping under the cab... Gary

Re: Exhaust?
it currently has longtubes on it, just well one is broke, and looking for options on headers if i cant save em. and i was thinking it having dual glasspacks, with them dumping out right before the rear fender, or them dumping right behind the rear fender, as i have some salvagable pipe from the old exhaust.

Re: Exhaust?
Personally, I would spend the money on the 2 1/2" rams horns and move on down the road. I replaced my Heddmans with the 'vette manifolds and could no be happier.
I'm going out of my way to try and get a set of big block repro 'vette manifolds installed on the 427 I'm building for my 69 short step. Should make plenty of power, at least for my goal of 350 whp and be quiet and leak/maintenance free.
