Nothing looks cooler than a huge tip completing your exhaust system. The aFe Power tip is constructed out of high luster, polished 304 stainless steel and has a slash cut with an aFe Power logo laser etched into the top of the tip. A drain port on the bottom keeps rust and corrosion away. This tip has a 4" inlet, 5" Outlet and is 12" long. It can either be bolted on or welded on.
