Drilling exhaust system

[wendigo]

Take the exhaust of, drill holes on the opposite side of the pipe to the dent. Get some metal rod (old bolts?) to feed through the hole, and bash the dent out from the inside.

Could then get one of those exhaust wraps for leaky car exhausts to cover the holes and use that as a stop gap measure till you can make more permanent arrangements.

Personally I'd leave of doing anything till you can do a proper job on it. Otherwise you could end up going from a functional exhaust to a totally rooted exhaust.

When it comes to repairing it, you're probably better of gas (or Tig) welding it, as opposed to using a mig machine. Less chance of getting metal building up on the inside of the pipe (hence restricting gas flow in the pipe). Another usefull side effect is that you'll be able to use the gas torch to heat the dented metal up to shape it easier.

Just my 2c....

And now, for the ONE MILLION DOLLAR PRIZE, name one other material vacuum cleaner pipes are made of.

Mine's plastic, though now I realise thats a farking dum question when I used to have a metal one I bashed my brother with. Where can I claim my prize?

Where can I claim my prize?

On the moon. Crater number IZ557-84b. It's there waiting for you. Really.

I love the dodgy fixes. Yeah you could get all "properly" done but that will be more than a few bucks. I'd use a slide hammer (but I have panelbeater friends) failing understanding mates with the right tools there is nothing wrong with the suggestion of drilling through the other side and tapping it out. It won't be round but if you use lots of little taps and get the feel for how flexy the pipe is before going hard out I doubt there would be any more restriction than before. Go to a panel shop with one cold beer at the end of the day and point at the hole, it'll vanish in a second. Then off to Supercheap cos they have heat wrap on sale at the moment and hot gasses flow noticably better than cold. You'll have fixed, legal and safe race pipes for cheap as out of the sorry incident. I hate diesel, I swear the tank caps they use have breathers or something thta lets it spill out on corners when the tanks are near the top.

dude tis easy --loan the bike to mark --mark fucks the rest of the bike--problem solved
AS AN ALTERNATIVE --See a panelbeater and get a loop of mig wire welded on to the middle of the dent--Use a gas torch and heat the pipe up cherry red --using an appropriate pulling tool pull on the loop--the dent will come out --once its at the "about right" stage --go have a cuppa till it all cools down--then cut the wire loop off.
