Hi i have recenly gotten an exhaust leak on my 94 Vx
its on a flexable pipe located on the down pipe rite before the cat
i tried to bondo over the mesh but only lasted a few days any ideas on how i can stop the leak
I suspect that the heat there is too high for even a "muffler bandage" repair kit you'd get at an auto parts store, let alone bondo. You probably need to replace that pipe.

It's not the heat it's because the pipe is designed to flex with engine movement. Hence the name "flex pipe". I also had that problem on my monthe-in-laws Accent. It was replaced for free by the dealer as part of the emissions warranty.
Out of curiosity is thermal expansion large enough to be one reason for flex joints?

The OEM VX exhaust doesn't have a traditional flex section, much less before the Cat....I don't believe that you have a stock exhaust on your VX.
#11 in that picture is the stock VX downpipe coming from the Maniverter.
The stock system has spring loaded bolts and rounded graphite gasket on the downpipe from the exhaust manifold that attach it to the B-pipe and the rest of the system to tack up any rocking motion.
IIRC, the stock diameter of the OEM system is either 1.65" or 1.75"

no, it's for engine vibrations as well as drivetrain flex (motor/transmission mounts. yes they're supposed to move.)

Thanks. My backup mechanic (when my main guy's on vacation) mentioned thermal expansion as well once when I was having a flex section replaced, but I was skeptical that the lengths & temps involved would really make it much of an effect.
