This NASCAR-inspired dual exhaust system, customized by Hot Rod Chassis & Cycle for the 700HP Raybestos GTO-R has a cross-over tube design allowing more mid and low end torque from the LSX 454 engine, and optimizing ground clearance. The free flowing custom racing cut-out allows the engine to breathe easy when on the race track, and offers a block-off plate option to quiet the GTO-R when it visits the suburbs.
