Diamond eye downpipe HELP!!!!

[Dirt rider1]

I bought a 3" down pipe from diamond eye for my 1997 powerstroke. I'm tryin to get the old pipe out and haven't had ANY luck. I've read that I'm supposed to cut the pinch weld and beat the firewall back, but what is the pinch weld and where is it?!
Please help!!!

Thanks

Cut the top of the oe down pipe off. Like cutting off the head of a snake. Use a sawzall.

You can either cut the old pipe out, pull the motor or pull the cab. Most of us choose to just cut the old pipe out, it's much easier. Once the pipe is out, look up from under the truck, you will see a seam in the firewall where two pieces of metal meet at a 90. That's the pinch weld that you will need to massage before the new pipe will fit.

you can also cut it right before it goes up between the firewall and the motor and then pull one piece out of the top and the other out the bottom and as for the pinch weld use tin snips or the sawzaw and make little cuts in it makes it much easier to fold over and fold the weld down not up

What about using an angle grinder or reciprocating saw??

A sawzall is a reciprocating saw.

Keep in mind this is a farm truck and the parts that he installed made it easier for him. The rest of us would use the correct parts but anywhoo I like this guy because he's down to earth and shows as much as he can.

I used a scissors jack to push in the firewall. i hooked my impact wrench up to it and it went pretty smoth.

angle grinder would work if u could get it up there i used sawzaw with 12 inch blade made 3 little cuts in the weld and then folded them over with a 2x4 and a hammer

BE CAREFULL cutting the downpipe with a sawsall if going from the top down(if possible go up from the bottom). i cut my pass up pipe by accident while getting carried away and angry.
