Hey Soren, only because I've seen you mention it a couple of times.... be careful with the steel wool, that stuff is more flammable than drunk at a bonfire. Little spark or backfire out the pipes will prolly light it up like a roman candle. I don't think a brief fire in the pipes would really damage anything but shooting a flaming fire ball out the back into the lovely countryside or better yet into the grill of a tailgating cager might cause a few probs. Wait, I like the tailgater part, carry on.
