Default =( Damaged Exhaust Pipe

I had a accident the other day and was curious to what were some of the disadvantages to a bent or smashed pipe or missing stinger? Do I need to go buy another pipe or can I just keep using this one? I heard of a method years ago where you could fill up a badly damaged tuned pipe with water and seal the stinger and manifold and put it in the freezer and it would expand, but I don't think I will try that.

1st I feel for you I hate when that happens.

The freezer water trick does work but for that amount of damage you will have to do it a few times to get the stinger in better shape.

The only problem I have had with the freezer remedy is the more times you have to refreeze it the more the whole pipe will swell.

I would give it a try, what you have to lose.

Maybe put a little JB weld between the stinger and pipe next time

No need for the freezer on this. simple fix here is heat the pipe up eg run engine, heat gun, heat torch etc grab the stinger firmly and pull it out it's aluminum so will be soft once warm just take your time doing it should be ok

the heat method seems like a good idea for the meantime...

Heat is definitely the best answer. I personally take a heavy screw driver that fits through the stinger and gradually pull out and to the left. Do this slowly with even force. I think you will be amazed how the pipe will pop out around the stinger. However make sure you don't go to far in the direction of the pull out and to the left. Because if you try to bend the stinger back into the correct angle, the pipe will collapse once again. I will tell you I have a pipe I am using on my engine now and I have been hit twice on this pipe and both time I have fixed it and the pipe works just as great as before.

I have tried the water and the freezer thing and just never had any luck. I have had friends that did this back in the eighties and they did it successfully. I just could never get it to work. But that is just me.

It will work out for you. Just heat, time and patience placed all together at the same time and you will save this pipe easily!!

Have Fun and Good Racing!

The freezer trick does work but you have to keep an eye on it. Like others have said, it can swell up if left in the freezer too long. Heating it up sounds like a good idea..................
