Hey I'm sorry if this has already been asked I searched and couldn't find anything. So I have a '13 Si and when it was new I put a Skunk2 cat back on. Now 6 years later I just failed my inspection due to an exhaust leak on both sides of my resonator. Long story short I need to replace the gaskets but due to 6 years of heating up, cooling down, and rusting I can't get the bolts out. I have sprayed a can of WD40 on the bolts over the course of a week and have made no progress as to removing them. Does anyone have any other ideas how to get these out? I have limited access to good tools at this moment due to me being stationed away from my house. Any help will be appreciated.
