URGENT! Muffler tip is melting bumper!

Schultze has a 3" Magnaflow catback installed; we had an accident and he just came home from the hospital.

I have to limit the amount of time I drive Schultze because when I went off the road and hit the ditch, it bent the exhaust hangers and the exhaust tip is starting to melt/bubble the new rear bumper.

The collision center is making arrangements with a muffler shop to have it fixed. The initial solution is to have the muffler shop cut the muffler & a short length of pipe leading to the muffler and weld into place a downward-angled pipe leading to the muffler. The end result...as they've described it...will lower the exhaust tip approx 1/2"-3/4" below the curved opening on the rear bumper. Does this sound like the proper solution to the problem? Oh...and they plan on removing the damaged bumper, repairing it & repainting it. However, since the bumper cover itself is plastic, I'm concerned that it won't look right...what is used to repair melted plastic? Is there such a thing as "bondo for plastic"?

Can someone recommend a heatshield product that I can tuck between the exhaust tip & the bumper until the repair is done by the muffler shop?

Thanks!

Erika

Look at the Thermo-Tec Heat Protection Products (heat barrier adhesives)
These work very well for what you are describing . A piece could be cut and attached to the bumper out of site and give the bumper the protection from melting.

Look at part number THE-13500

It is the cooper s tailpipe surround, mainly for looks, but should be a heat sheild as well.

Hi!

Thanks for the reply...I should've been more clear in my original post...

I'm looking for something that can be purchased locally as a short-term fix until the muffler shop makes the adjustment.

I have a 'vert but I have the Magnaflow on it. I had the aero kit installed and was worried (and read) that the tips would contact the aero bumper and melt it. So I had the tips cut off, about 2 inches of additional pipe installed and then had the tips reinstalled. I don't have any pics but it looks fine.

Drop the rear hangers and add as many washers as you can between them and the body. It will hang lower but it may be a quick fix for a few dollars worth of washers.

You might look for a flame shield blanket at your local plumbing supply or hardware store. Used to protect surfaces from the heat of the torch when soldering pipes. Should be ~$20.

Is it the hangers that cause the misalignment in the exhaust? Shouldn't that be being repaired rather than hacking the pipes?

Doh!

That's a great idea...guess that was another forest/trees moment for me!

The "solution" described in my original post was given by the collision center; if there's a better solution to the actual repair, I'm certain that the muffler shop will do what's right.

I'm going to try to take pics today...
