I searched and couldn't find if this was a good idea or would lead to issues. I added Vance and Hines slip-ons a while ago and it was really difficult to remove the left side OEM muffler, even after soaking the area overnight with penetrating lubricant. At the time, I installed the slip-ons "metal to metal", but now I will be removing the mufflers to install the IDS and I was wondering if adding some anti-seize would be some preventative medicine or would antiseize allow the muffler to "slide around" making exhaust leaks. I saw some posts that had issues with putting antiseize on the bolts of the pipe clamp, but nothing on where the slip-on muffler is squeezed onto the exhaust pipe. The flange to my OEM left side muffler is/was really expanded/warped/bent from the removal process and I am trying to prevent this in the future. Thank you for any input!
