Swapping to headers.

RRoriginals · Jul 8, 2011

Hey guys, I have a 1973 Plymouth Roadrunner, 400cid 6.6L.

All original, but I want to replace the exhaust manifolds with headers and do a full switch on the exhaust itself.

Would these headers:
http://www.summitracing.com/parts/SUM-G9041/

and;

any of these pipes:
http://www.jegs.com/p/JEGS-Performa...Dual-Exhaust-Kit-w-o-Mufflers/751648/10002/-1

Be a good match? Or can you direct me here, I haven't touched anything with headers, also I don't have a fortune to spend on a new exhaust, but I need it.

Also, yes I know one set or two are side exits, which I don't mind.

the summit set won't fit your engine
the jegs ones are really crappie. anything with flex tube is not good

RRoriginals · Jul 9, 2011

99.9% Sure that the Summit set will fit.
..especially when you check which applications it fits.

6.6L/400CI.

And I'm not too concerned about the "Crappy'ness" of the system, It's not a show car, FAR from it, it's just a driver once and a while.

Back to the real question: Will those headers and any of those systems match up?

if your 99.9% sure it will fit then what more are you wanting?

Hedman 78030 are the best fitting headers for a b-body. Pay the extra bucks for ceramic coating...It's worth it

Tti

I'd suggest TTI if you can afford them. Bolt right up. Get ceramic coated.

I wouldn't suggest the Hedman elite header 78038. They don't fit worth a dam. I won't make that mistake again. Not sure about the 78030.

I guy I know tried ceramic coated Hookers in a 73 RR. Wouldn't work with a 400 or a 440. 400 hit linkage, 440 hit trans. He beat the hell out of them trying to make them fit, now they are unused but almost worthless.

i'll second the recomendation to use the TTI headers

quick63 · Jul 14, 2011

TTI are the best fitting and are well made. I run them on my '63 NSS Maxwedge. Worth the money...I have had 2 sets of 78030 Hedman and had no problems..big block 4 speed application. Hookers earned their name..Worst fitting made in Mexico. I had a set of competeiton 2'' hookers on my 440 Challenger and had another set on my '63. Fit was not even close.

Summit headers are private label headmans. I've used about 8 sets of them on small and big block B body cars from 68 to 74 and never had a problem with them.
