Every 42 Draft Designs exhaust system is scratch-built from straight tube and flat steel. Our team of professional metal fabricators cut, bend and form raw materials with precision. Piping is mandrel bent in-house using our Baleigh CNC mandrel bender. Flanges and brackets to fit each system are cut on our OMAX waterjet. Additional forming takes place using our Huth end forming equipment and our Dake 100 ton press. We use ONLY the finest North American made materials proven to stand the test of time.
