Summit® makes electric cutouts simple. These universal 3.00 in. cutouts come with a wiring harness and switch. Just bolt the 6061 aluminum unit onto the end of your dump pipe and hit the switch, and the butterfly plate on the 2.50 in. exit opens to reduce backpressure. If you've got a dual exhaust, grab our special combo package that includes two electric cutout units, plus a special wiring harness with a single switch to operate both cutouts at the same time.
