I was wondering if there is anyway to fix the old gaskets on a viper, the ones between the manifold and pipe and the ones between the pipe and can. I was wondering if you could put that orange silicone-type stuff that race cars use for header gaskets? Is there any other way to fix them somehow, i don't really want to spend over $70 on new one's.

If not I will just pick up both gaskets and 4 new springs from Port.



I need parts 4 and 6......


4. SKU: 8CA-14714-00-00
GASKET, MUFFLER

6. SKU: 8EK-14714-00-00
GASKET, MUFFLER

the two problems i see would be from the grafoil type material the doughnuts are made of:
1 they squash down over time relieving the amount of spring pressure holding the pipes tight
2 don't know how well the silicone would stick to the graphite if at all
it may buy you some time but i think your gonna have to part with the $70 in the end
 
I also have a srx, my gaskets are leakfree but starts to look a little ugly. To buy new ones is around 200$, this is ridiculous pricing. Nobody knows an other place than Yamaha dealer to buy these grafoil rings? Grafoil rings must be used in other applications.
 
The Donut Off Of The Exhaust Manifold Can Be Found At A Local Carquest Store. There Part Number Is 9051. It Costs Around 3.00 Bucks. It Worked For Me. It Is A Little Different But It Worked. Hope This Helps Out!. This is for the single piped viper.

Alright, I'll go have a look, thanks.

I've used this on exhaust donuts to ensure a good seal on donuts that are less than pristine. Make sure you let it set up over night or else any exhaust pressure will blow it out before it has a chance to set up. I also lay a beed on the springs (as installed) to reduce vibration. I've used the orange stuff too but the black is less noticeable.

I just bought one of each of these, ultra black and ultra copper, and the black one is only good to 500*F intermittent, and the copper is good to 700*F intermittent. Is either of these enough? I thought the exhaust would get a lot hotter than that? What is the egt's at full throttle, 1000*-1200*?

USE the Copper sealant. I use this everywhere on my triple pipe setup, works awesome! I use it metal to metal, metal to gasket, and gasket to metal. Just make sure to let it setup for a bit (day) before you fire it up. Im guessing my egt's are around 1250 ish and this stuff still keeps working. Really egt #'s arent what you should be worried about, its just the pipe temp or surface temp of what you are adhearing to.
 
P.S I would not use the black anywhere on exhaust. I tried it and it melted at pretty much an idle. The ultra copper is far superior.

Yeah I know, but the higher the egt's the hotter the pipe gets.

Yes, you are correct, however the pipe temperature is not a linear function of the egt numbers. Cooling factors are air velocity on the outside of the pipe, underhood ambient air temperature, and the transfer of heat in the pipe.

For example, a increase of 100 degrees of EGT numbers will not increase the pipe sealing surfaces in increase of 100 degrees.

Beside all of this heat transfer mumbo jumbo, the Ultra Copper should work well for your situation, especially if you are not triple piped, because your ambient air underhood temperatures are a decent amount less than that of a triple piped monster.

I'm aware.... I'll let you guys knows how it goes when I try it out.
 
Why don't you guys just buy the high temp yamabond stuff at the dealership, like 13 bucks for a tube and its for this type of application. I use it because my gaskets were getting rough and it works like a charm!!!
