Thanks for the info. I will mod my mount and start mocking up parts.. I have to make a hard decision on these.. I really wanted to use a burns style collector as they are so nice but that could drive the price up another 450 in cost over just a simple collector like you see so often. I looked at headers by eds website as they offer a bunch of options but I can buy everything locally for about the same price and I can locally source all the flanges as well.. So to meet my target of 1500. It looks like it will be the simplier collector..

What is everyone's thoughts on this?


By simpler collector do you mean a formed collector vs. the nice welded ones with inner guide that Burns sells?

I would love a set of SS headers for my 3.2 with heat exchangers....I agree with wndsnd, design the best and offer with and w/o heat.

It began to rain in Baton Rouge and it continued that night, through the next day in New Orleans and into Florida.

I was excited to be able to pull my red lever on the center tunnel and crank the upper dash lever to the right, middle to the left and lower to the right and clear off my windshield in a few seconds.

Heat isn't always for heat... something to consider next time you say you don't need heat. (IMG:style_emoticons/default/wink.gif)


(IMG:style_emoticons/default/agree.gif) ,its about defrost but really that's the wrong term in a warmer climate,you still need something to move air over the inside of the screen regardless of where you live.

Yes and no.. It would still be a welded assembly but much more like a formed collector..

FYI I was looking at Armondo's 914/6 GT site and saw this picture of the Monte Carlo 914/6 GT's heat exchangers...never seen anything like them before. It must have been so they could run defrost etc at the rally:

I think I know what you're talking about but do you have a picture or link handy? I'm visualizing the collectors you can readily make with a jig in a bandsaw/chop saw like these.

Another option to heat exchangers is seat warmers. I plan to do that when I purchase new seats... actually I prefer them over heat. But it also doesn't normally get colder than 50f here in Cali.

Cool. For the $450 it's a no brainer to me at least to go this way. (IMG:style_emoticons/default/smile.gif)

Well I have refined the oil tank process so I should be moving on to this project shortly though I don't know when this will be done thinking another 6 weeks before I get a good handle on them

Sounds good to me, 6 weeks seems pretty quick to me (I'm a procrastinator)

Yes exactly


Well, I'm happy that your oil tank project is finally in production.
Now back to the exhaust. I know the main paradigm is equal length headers.
Are you going with this same mind set? I'm wondering if you have access for some dyno test on a stock engine vs say George's European headers that have been around for years - especially since the header is currently at the design stage.
Good luck with your new project.

So this project is going to start soon but I have been thinking maybe what the real market would be to make the heat exchanger kits for current headers?

So for an example I could make them for bursch or Georges etc as to not reinvent the wheel..

What does the brain trust think about that ?

If they work with Marty's (MSDS) headers, I'm game....think they'd work well (produce good heat) with his ceramic coated headers?

If not, I'll just get a whole header/heater box setup from you (IMG:style_emoticons/default/biggrin.gif)

I actually think the idea of a heat plenum that would fit to the existing header choices to be a good idea. As you say, why reinvent the wheel. And all the folks out there with the Bursch headers (I think those are the most common after market ones out there) would have the option of adding heat to there existing headers for way less than an all new set.

I would also suggest looking at a very abbreviated design. My stock set with the "full metal jacket" treatment makes lots of heat.,, more than needed except maybe in the most extreme situations and who among us is out driving their sixes at zero degrees??

The aviation style "heat muffs" are much smaller ( https://www.aircraftspruce.com/pages/ep/car...rsheatmuffs.php ) and the single one in my plane makes a lot of heat. Besides price, the biggest benefit might be that a smaller, well engineered muff would allow for a lot more room to adjust valves. I have not attempted a valve adjustment with the stock HE's in place (is it even possible??) but was able to do one with Bursch headers in place.

What say the masses (IMG:style_emoticons/default/confused24.gif) ??
