This Flowtech dual exhaust universal fit cross pipe incorporates Flow Intensifier™ cut-outs for a quick and easy transition from "thru the mufflers" to "uncorked and unleashed". This system is for you if your ride punishes the pavement on both the street and strip and if you run tracks with and without sound restrictions and don't want to be hassled with unbolting your mufflers. The cut-outs are configured to work in either a side or rear exit configuration. The removable Flow Intensifier incorporates a solid diversion tube with a concave surface that provides an inner pipe wall for smooth exhaust flow when installed. Remove the three wing nuts with the included track tool, slide the Intensifier out and you have a free flowing exhaust!
