Exhaust question?? Is this part a muffler????

[mmandley]

Have the same type of muffler on my 2004 LSV and it is leaking fro the drain plug at the bottom of the muffler. It is a small hex head bolt, and appears to go into fiberglass. Can I just up size this bolt to make a tighter fit, or is it backed up with some type of metal inside and need to tap it? Thanks

Yes you can upsize the bolt no issues.
