Hello, I am doing a DIY cold air intake and i am gutting out all of the old stuff like the charcoal canister and other not very important air hoses going into the air box. I noticed my renix has a wired hose from the exhaust manifold to the intake to warm up the engine on cold starts. Well I am getting rid of the intake box and now the hose is hanging around letting out exhaust gas. What is the best way to cap this off? I can't see to find any good write ups fixing this problem. Thanks guys!

Additional notes: No I do not have a welder! ( I wish I had one)
