Cobra was a fairly big pipe manufacturer WAAAAAY back in the day.......probably before most of you peeps were even born. They have since died and a cobra pipe is something you only come across now and then on Craigslist on older ATCs and Honda ATVs.
They were a decent pipe for their time, but are inferior to modern pipes. They are basically like DG.
