Header flanges?

Recommended Posts

I'm looking at building a full-flow header with a cleaner collector than the one that came stock. I haven't done the math yet, but the tubes look like they are too long before they hit the collector, and they are rather poorly made. I'd like to find a flange for the header that i can use to build a header and good collector/tailpipe. Is there a good header made, or a header flange? I have the 650 two cylinder.

I know of NO aftermarket headers. I agree our header is more of an exhaust manifold than a header. The tubes on the 1100cc are also different lengths thus a poor header. A real header would also produce an entirely different sound, more like a race car.

I really don't know anything about headers but I do know that the header design is a function RPMs and the use of the engine. A high torque low RPM header is going to be different then a high RPM high HP header. I did run the numbers on the intake tubes at one point and came up with, if I remember correctly, about 3/4" ID for a naturally asperated engine of our cc's for max HP, can't remember the best length, but I feel this would be detremental to low end torque. I assume that the sound of a high torque low RPM header will sound sort of, how do I describe this, PUTTY sounding with putts that are real hard hitting while I think of a high HP higher RPM racing header sounding like Rocmoc says, a smooth very consistant from cylinder to cylinder buz. How do you describe a sound? Cleaning up the ports would be my first step but then again that is part of building a good header. The port passages in the head itself can be also improved but you must be very careful to not cut through into the coolant chamber.

Hi Romoc we have found that the stock cast iron manifold puts out more torque on the lower end than the header. Just something to think about.

Do you have any stock manifolds for sale?

I don't have the four cylinder, I have the two cylinder. The pipes are OK from the head, as far as i can tell, but the collector looks like booger welds, as does the turnout to the muffler. I'd like to start fresh, it is easier to get clean welds on fresh metal. The tubes are long enough for good torque, I just want to get a clean exit.

Hi Guys

All 2011 Troopers will come with the cast iron manifolds.We are trying to get them but China Joyner is not being helpfull.We are going to see if a header dealer will make some headers for more toque on the bottom end.Let see what happens.

Should be the same process as in the articles I posted. Four or two should make zero difference. Just takes time & money, LOL!

Hey Rick,

I take exception to what you just said about Joyner China. The way I see it, Changzhou Joyner is contracted to JMC and can not deal directly with you even though they would love too. This doesnt make them not helpful, it means their hands are tired. Lets all just remember that the Joyner manufacturers are in no way part of what has happened in North America, period. They could not possibly foresee that JMC would simple not order units or parts. I dont know of anyone that blames them at all.

This last 12 months or so has done nothing, other than to make them more determined to make sure contractual agreements will be 100% vetted in the future. Talking out of tune Rick, when Joyner can not possible help you, will really get you in their good books aye!

I think you may of made a typo and should of said, JMC is not being helpful.

Cheers Mike.

On the question about Joyner not being helpful, I meant that many vendors they used were not very helpful. Yes we all know JMC is not doing its share.I was Joyner # 2 Dealer in the USA when John use to own it. I know that they have a contract with JMC and Joyner Could Not Sell to anyone else.

Thanks

Rick

Cool, that clears that up.

I sent you a pm.

Hi Rick. I tried to send you a PM, but the computer said you couldn't accept anymore messages. Shipping by mail would be approximately $30. If you are interested I will need more information.
