Hello,
I have purchased the cat-back components for my 1995 Passat VR6 - Walker brand. I noticed on the 'suitcase' or center muffler there is a bad quality weld on the outlet pipe. There is a crevass underneath the weld or a place where the weld overhangs and does not contact the pipe. I do not know how to explain it better than that. My general question is;
Does anyone have an idea how muffler welds could be potted, sealed, protected or otherwise improved to help longevity? I first thought of JB weld but learned that that should never be put on exhaust systems because they get too hot. I have "muffler mender" by Victor Products but I am not sure if that product would work in the long run. Isn't muffler putty known for being only a temporary fix? I only intended to use this product to seal the new joints under the clamps.
If I cannot find some DIY treatment or product the best I can think of is to take the part to work and have a coworker add some weld in this one region to seal up the open area. I live in the midwest- Wisconsin so salt attack is the concern. btw my stock muffler has lasted 10-11 years.
Thanks in advance!
