Is Oxygen/mapp enough? or do i need.....
Is Oxygen/mapp enough? or do i need..... More or less, Im trying to seperate my exhuast... 3 inch td slip fit, from the header. It was slip fit, and standard exhuast clamp, so its bent a tiny bit on. I have the exhuast clamps off, but i cannot seperate the slip fit. I was told oxy Aceteleyene, get it red hot, and pull it off. Well doing some reasearch i came across the benzomatic mapp/oxygen torch kit which claims can get as hot as 5300F, ive seen alot of websites say Oxy Aceteleyene gets as hot as 4900, and some say 5700. Im wondering if i can get the mapp/oxygen setup, save a little money, it seems mapp is alos safer, cheaper, and easier to get, and can get almost as hot.
Is this the best way of getting the slip fit apart? If this doesn't work, im going to cut it off past the header. I tried heating it a little with propane today, but that just wasn't enough.
Thanks in advance, Chris

get the car on a rack and use a block of wood and a 5lb hammer.... my slip fit does this all the time... just keep hitting it... heating that thin of pipe thats slipped over the other will make them both get hot and wont change a thing.... use the hammer... its your friend

mapp/oxygen will/can blow through thin metal as well as weld metal so its a great option. for all you guys beating the exhaust with hammers......i know now why my slp y pipe that came with the car is bent to hell and back and needs to be replaced. it looks like some idiot decided to go postal on it. now its caved in. kinda defeats the purpose of having it doesn't it?
