13mm open wrench and just keep loosening them. The bolts will push the hotside from the center section and you might need a rubber mallet to persuade it a little. You should also mark and/or note the orientation of the hotside so you dont have issues with your downpipe lining up or your wg actuator rod getting kinked.

 

i used a open end wrench if i use any more force i will strip the bolt i used penetrating lube and hit it with a hammer to try to loosen it but it didnt work

 

Have you hit it with a mans hammer, or just a little one? Under the pressure of the bolts and multiple hammer blows, I've never had one not come off. Those bolts will take quite a bit of force before they strip (they're high grade M8s), you can can apply some grunt. Just don't go crazy...

 

You could probably also torch it if you are afraid to snap it. I like using mapp gas to heat things up. You might also consider that it may be crossthreaded if there was a chance it was taken apart once before.

 

well i just went back at it finally i got it to come off after beating it acouple times thanks for all the help
