well I have been looking into having my 500r pipe repaired and i decided to do it myself. I have a new pipe coming so what do i have to lose.

here is what it looked like originally

http://picsorban.com/upload/500rr.jpg

i took a plug that would fit inside the inlet to the pipe. I then put a vise grip on to make sure it could not fly out. I then took a 1 3/4" pipe and welded a air hose fitting to it. i took a car radiator hose and connected it to the outleat of the pipe and the other end to my air fitting. I then bled the air tank down to 50 psi. i connected the air hose and SLOWLY opened the air valve to pressurize the pipe.

MAKE SURE THE PLUG IS NOT AIMED AT YOU

then i just heated the dents cherry red from the outside in.

use this at your own risk

be careful and were all safety gear as melted steel will hurt / blind you if you have a blow out.

I have done that at the shop I used to work at. Plugs on both ends, one plug had a air valve on it. When that plugs goes, its goes far and very fast. It flew to the top of 30' ceiling and made a indentation to the foam lined ceiling. It sounded like a gun going off, when it blew.

yea, i blew one out that is why i did it like this the second time :) the plug is down in the pipe and the vise grip is clamped to the inlet. worked very well. jsut keep the plug aimed away from you at all times. it could be deadly.

What's the vice grip holding in the inlet? Doe you put air to the end that clamps with the silencer? I need to fix mine a bit too

how long do you have to heat it for? how much area around the dent do you have to get red hot?
