I still cant get the damn bolt off (connects downpipe to cat)

Its very rusty and it may be stripped, tried air gun, tried all my strength, whats the cheapest way to get this bolt off?

 

This is a replaceable bolt and nut right? When I have a problem like this, I just grind the bolt head away and the remaining piece with the nut comes out.
But this is only if you can buy a replacement bolt and nut.

 

Get a blowtorch.

 

use a torch
or use a air chizzle

 

type torch doi need?

could i use a pencil torch gets to 2000

 

Head for the hardware store, grab a can of mapp gas and a mapp torch. You'll use it more than you know.

 

how much that costs roughly?

 

the bolt is threaded directly into the flange of the cat...all you've got is the head on the bolt; unfortunately there is no nut. trust me, i would have ground that S.O.B. off in a heart beat last weekend if that was the case

 

I hear pb blaster is pretty good. But really all I can say is good luck.

 

it's starting to look like vice grips, blow torch, and a weeks worth of penetrating oil is going to have to work.

 

so i cant get a replaceable bolt for this?

Damn so i cant cut it ahah

 

It's a b*tch. Unfortunately, almost all of us who have done exhausts have gone through this, and quite a few of us have had to go through the same exact ish with that bolt.


If you were closer to DC I'd get you in a shop with a lift and for 4 bucks we could get that sucker off.

 

I know I'm gonna run into a similar problem. I was under the car last week looking at the stock cat and I noticed something a little disturbing. When I had my catback put on, the brilliant welder at the shop decided to weld the bolt head/nut to the pipe when he welded the pipe onto the stock flange Looks like I'm gonna have to grind it away....

 

^that's really messed up, I feel for you man.

 

just take it back to a shop and have them cut and reweld everything for you.
