Chrome & Black Exhaust Tip Chrome Dual Slash. How about this chrome and wrinkle black exhaust tip for your favorite ride? It is about 13 1/2" long with a 2 1/2" ID inlet so it will slip over a 2 1/2" OD tail pipe (slightly tight). The outer ends are 3" OD each. It can be clamped or welded. This is the heavy duty muffler shop version. This listing is for one.
