I live in New England and consequently my exhaust rotted all the way through at the coupling that comes before the muffler. I cut the coupling out and welded on a 1 3/4 exhaust connector from the auto parts store as a temporary fix (cost $3) before I get a new exhaust system. Unfortunately, I couldn't get to the top of the connector with the welder, so there is some exhaust gas leaking from the top.

I'm driving from Boston to Cleveland, to PA and back to Boston this weekend - at least 1,300 miles - and was wandering what recommendations people had to reinforce my hack job that would stand up to the weekend. Next week it's getting the new exhaust.
Any dangers to the car if it's got some of the exhaust fumes leaking out?

My AC doesn't work so I drive with the windows open so I'm not too worried about fumes in the car.

Thanks in advance.

 

there are ready-to-use kits at most auto parts stores. enough for a patch job with sealer and some sort of heavy duty tape to wrap around the pipe and hold the sealer in place.

but since we're talking temporary hack jobs... two large screw-type hose clamps, an aluminum drink can at least the same diameter as your exhaust pipe (or bigger), some good scissors or tin snips and some sort of high temp sealant (there are sealants made for exhaust repair, but for short term fixes even some high-temp RTV would hold for a few days). cut the ends off of the can so that you have a flat-ish roll of aluminum. cut the can lengthwise so that you can wrap it over the pipe. coat the inside of the can liberally with the sealant. hold in place with the clamps positioned as close to the weld joint as possible but still on smooth section of pipe (the clamps should lay flat against the pipe all the way around.) some overlap of the edges of the can is a good idea for an ideal seal.

like this but better:

 

Awesome, thank you. Will something like this work:

Ditto the above^^^ old school beer can repair, this type of exhaust pipe repair has been used for as long as there has been beer cans, the sealer just makes it better, [in the old days it was a piece of asbestos] then the beer can wrapped with bailing wire to hold it all in place, my dad used this on more then one of his cars and not just for the short term. 94

 

looks good!
