Summit Racing™ steel transmission crossmembers allow you to run a true dual-exhaust system with most popular GM transmissions. They have a patented double-hump design, so you don't have to compromise ground clearance by running pipes under the crossmember, and they're a complete bolt-on deal—no custom fabricating or realignment is needed. The parts are made from 1/8 in. thick boxed tubing to handle the frame-twisting power of big blocks. Order the crossmember recommended for your vehicle and transmission application.
