I just got my b-pipe today (no muffler yet) and I notice alot of oil/gunk coating the inside of the b-pipe as far as I can see, and an oily substance on both end flanges. Is it supposed to come from the factory like this?? For some reason, I was expecting the inside to be as clean as the outside. Do I need to clean this crap out before I install it on my car, and if so, any suggestions on how to clean the inside? Thanks all, and happy holidays!

using it will clean it out. Just bolt it up, the heat will burn it off just fine.
