I noticed a leak in my exhaust system this morning while it was cold enough to make the exhaust gas visible. After looking into this afternoon, I have found that the seal between the front of the muffler and the back of the cat is shot. I can't get it tight enough to stop leaking completely, although it is a little better now. My biggest worry though is that I noticed a lot of water being sprayed out where it is leaking. What is causing this and what can I do to fix it? The only exhaust mods I have done are a Calmini 2" cat back and a RRO Mega Flow Filter.
BTW, how much will this leak effect my power until I can get it fixed?
Thanks in advance.
