Well I have the new pipe on but my stock header has some hose coming from it near the engine, the new one doesn't. I couldn't get the hose off the old one so I cut it as close as i can. None of the header pipes I have seen online have the little hose thing on it. My question is what does the hose do and what should I do with it now? Its not connected to anything. I haven't tested it out yet because my battery was almost dead and i'm charging it now.
