Being at school and having limited tools, I used a bit-too-small hex T-bar to try and get the stock exhaust pipe removed to install my new HMF, the ones on the stock exhaust hanger.. Now they are both pretty stripped, notto the point where I cant get any grip on them, but even when I try and push into them as hard as I can to torque the screw on in there, it just strips it more -.-. I was just impatient and had to work with my friends had, which is not much as you can imagine. Any specifc techniques you have used to get one of these suckers out? If I could cut off the top of it, would this work? Lubrication? Heat? Anything? Ahhhhhh! I am screwing up lately.
