The QTP QTEC 4-inch weld-on exhaust cutout Y-pipe is a welded fabrication fitting for 4-inch exhaust systems, intended to be used where an exhaust cutout is required. It supplies the Y-shaped branch to divert flow when a cutout is installed, supporting permanent custom routing or replacement work for larger-diameter exhaust setups that use the QTEC weld-on pattern.
