headers ?

I am in the process of doing the triple Stromberg upgrade to my 72 TR and was wondering if upgrading the exhaust with header would be a wise move? Will the header be more aggravation than its worth, are they reliable, too loud, and do they add any performance to a stocker other than the carb upgrade? If I do decide to go with a header and exhaust what setup do you recommend, because I would rather spend for quality than deal with constant service. The other consideration is my TR spends some time on the freeway so I really don't want it to be extremley loud.


Thanks
 
Headers came on my car. They are some of the cheaper mild steel ones. Since they were on the car, I can't address the difference in sound, performance or what not. Though I don't find them much more noisy.

But these things I have noticed:
1. They run pretty hot. So I would look at putting on a heat shield.
2. The ones I have aren't the best looking ones out there and I would recommend putting some header paint on them. I head that the wrap will mess up the mild steel.

Other than that, I have nothing of value to add
 
you want to get a 6-3-1 design, NOT 6-2-1. yes it is worthwhile.You want stainless 321 not 304. you want all 6 primary pipes the same length or as close to it as possible. If you go with mild steel, have them ceramic coated inside and out (i think this is the best solution since most stainless headers are made out of 304 stainless not 321 ). Decent mufflers will control the noise mostly,but remember to get the most out of the header you really need some head work. Tony Lindsey Dean (I apologize for possible mis-spelling) can fix you up from what i've read, but he is in england so it won't be cheap.

Something like this?

Not made or designed by TLD, but another guy in the UK with a lot of experience with Triumph 6 cylinder.
Definitely 6-3-1 layout.
 
wow! yes! now get it ceramic coated. (not jet hot) try Swain (the white ceramic for very high heat and heat retention). There are others, but cost is $$$$. There are now a lot of Cheap ceramic, do-it-yourselfers to avoid. You definitely need the INSIDE coated as well.Someone spent a LOT of time and effort to make those. I would expect the cost to be around $1200. If you got them for less, you got a bargain! Even in carbon steel.I bet those work very very well as long as the rest of your package matches.Spitbang, can you send me a PM with info on who made those? SWEET.

was it GT?

oops,sorry spitbang, i see you are in the uk. I'm sure there are many good ceramic coating experts there as well.

Simply bolting on more carburation will only increase your fuel consumption and make the engine look faster! .

Any addtional carburation will require a larger cam, and more efficient exhaust if it is to increase performance. You can simply bolt on the carbs but without the other modifications you're really just doing a cosmetic change...this opinion is based on my 45 years of making the same mistake several times!

I much prefer the stock, quiet lets-get-some-good-gas-mileage approach for a daily driver. If your car is simply a weekend toy then go for it...but be aware of the pitfalls.

When it comes to performance there ain't no free lunch!
 
My 71 Spit has headers and they surely aren't noisy. It's what the headers feed into that makes the music. Just MHO.
 
YankeeTR,

I have heard that is true with the Weber triple setup.

Sources say that the stock engine triple ZS carb setup with Goodparts manifold will give you increased throttle response & horsepower as well as returning good fuel economy. I know that is true with muscle cars but isn't the venturi configuration of the ZS carbs and properly tuned only going to feed the fuel that is needed?
 
When I started my engine mods, the first thing was the triple ZS carbs, with few other mods. I didn't go any faster, I just felt like I was going faster. Over the next year, I finished the job (kinda like Brosky is doing now) by having the head and valve work, roller rockers, headers, etc., etc., etc. Now I do go faster. Very satisfying for an old man.

Headers + Cialis = Priapism??
 
I have a set of headers on my 3 ,mild street cam ,TR4A intake manifold. They throw off a lot of heat so I wrapped the header(some say that will cause the mild steel to rust). I also installed a heat shield to protect the carbs. It IS loud ,theres no getting around that. But there's nothing like that old tractor motor at full song.:smile: I've also heard that work done to the head is where all the real power increases come from ; but smoother intake of air and freer flowing exhaust has to be worth at least 4-7 HP. Anybody think thats accurate about the HP ?
 
The stock exhasut manifold is supposed to be good for 150hp. The stock muffler can be pretty restrictive though. When I installed the Twin Sports system on my stock engine with stock exhaust manifold, my buttdyno said it added a few ponies. Don't know for sure. The sound was nice, throaty but not too loud. Header made it louder, but it still quiets down pretty well at cruise.

It's kinda scary that thanks to the incessant television commercials, we all know what that is now ... /bcforum/images/%%GRAEMLIN_URL%%/grin.gif

why not jet hot? well it is a fine product, but because the exhaust is right next to the intake on triumphs, we want to reduce the underhood temperatures as much as possible and the ceramic coating designed for over 2000 degrees f also reduces the outside temperature of the pipes by a significant amount, more than jet hot. heat retension is also better and keeps the exhaust gas temperature inside the headers better, which helps the gas velocity to stay high,aiding in scavenging.
