Shorty headers
OK does anybody make shorty headers that fit a C3?
Are they more restrictive if say they are still hooked up to a 2.5" or 3" exhaust?
Long tubes are out of the question for my application..... I have my reasons.

I have chrome shorties running to a 2.5" exhaust and they were a big improvement over the old manifolds. The only thing I regret is not going with ceramic coated headers. That will change in the future.

OK how do long tubes compare to shorties in term of restriction?
Since 4 1.625 primaries has the same total area as a 3" exhaust.

Guru , A good set of long tubeheaders actually extract or scavenge the cylinders to allow better exhaust flow . Let me also point out that Good headers are extremely expensive , just check the prices on a set of Stahl headers . A set of correct size short shorties will certainly not kill your motor . There are pros and cons to each type of setup . A set of long tubes can be a real PIA as far as ground clearance , starter heat , and leaks etc goes . It is a matter of personal choice . There are some nice shorties available for reasonable prices ,,,,,,, that said be prepared for some pipe work to be done . Also take into consideration the style flange used by the header builder to connect to your pipes , I'm pretty sure patriot uses a factory style connection that is leak free .
For a built up engine [ read lottsa money invested ] GOOD long tubes are the ticket ! Otherwise shorties are fine and stock will do the job for you .

the flange isnt an issue.
And I have long tubes now but I want to get ride of them.
What are some good shorties to accomplish the mission.
I have heard good things about sanderson headers but they are cast Iron and I dont want the weight.

I think the advice of my header mfgr is correct, in that hooking up ANY pipe or muffler will about totally negate any header affects you would have had.....in other words, use headers for that cool look, or to make other things work better, IMO in my case, for spark plug clearance, still not great, or for light weight, or for....LESS HEATING UNDER THE HOOD....less mass to stay hot forever while the engine is off, and car sitting there....hood closed....as n daily driver...

I have "supposedly" opened up rams horns. The rest of my ex is so flattened and dented that I don't want to think how much power is choked up. There were some people "Bresenski" that made rams horns flow almost "advertised" as much as headers. I am concerned about ground clearance, underhood heat and performance. I know 1 5/8 long tubes would be best for power. I want to know how much I would be giving up w/shorties? I have a 74 w/duals, it should put out 400+. I hope we settle this. JMHO
