I'm trying to replace my Yana Shiki slip on - is there a trick for getting it off? This will be the first exhaust I've ever replaced - I thought it would be straightforward. I removed all three bolts and tried pulling and twisting it off, and also prying it off, with no luck. It seems that it is my destiny in life that a simple job always becomes complicated Maybe some spray lubricant? I get some, but minimal movement, when I tried. It actually seemed that the canister gave more than the mounting plate. I am willing to use an angle grinder if necessary. It's a 2002 with stock headers. I'll take any suggestions.

 

Put the bolts back in part way and tapped on them with a hammer - worked great.
