does anybody know if i could use jb weld to make a downpipe? i know it sounds kinda stupid, but i figured that if someone can jb weld a hole in the block then a dp shouldn't be that hard. can it stand the heat from the dp and turbo? i don't have access to a welder at the moment so if it works i could have turbo sooner than i though.

 

I wouldn't trust it.........

just take it to an exhaust shop.. they'll do it for cheappppp

 

thanks for makin me laugh

 

that was me with the JB welded block. if we-todd-did was up right now, I would show you a pic. :1
i wouldnt put JB weld on a down pipe though.

 

Epoxies both cure, and un-cure with heat. While you can use them on heads (Even the intake track all the way to the valves), and most block surfaces...
No. you can't use them with exhaust. Atleast not before the pipes cool down to never really get over 200*F.

You "could" make anything with an Epoxy. The problem is a downpipe would get hot, the epoxy would uncure & it'd fall apart.


(JBWeld is nothing mroe than an Epoxy)

 

thanks fo rthe laugh

 

It'll work fine until you start the motor.

 

Best thread ever!
