Chrome Exhaust Tip Mustang Slash Tip. How about this chrome exhaust tip for your favorite ride? It is about 12" long with a 2 1/4" ID inlet so it will slip over a 2 1/4" OD tail pipe (slightly tight). The outer end is 3" OD. It needs to be welded. This is the heavy duty muffler shop version. This listing is for one.
