I got this today, I have a little crack on my exaust manifold and i just wanna fix it quick without taking it to a shop to get it welded right now. does this stuff hold up that good? I know people use it when they tap their oil pan for the oil like to the turbo.....would it withstand the amount of heat that the exaust will be producing?

 

go to your local auto parts store they also sell an exhaust tape you can wrap around your leaky pipe

 

go to a local PepBoys and they have exhaust & header repair materials
