An exhaust system built with oval tubing may provide you with the additional clearance you need for your ground-hugging hot rod. The Granatelli Motor Sports oval exhaust components allows for the needed ground clearance, neatly placed exhaust packaging, all the while maintaining your engine’s true performance.

You can build one with the provided stainless steel straight tubing in 5-foot lengths, 90-degree vertical and horizontal bends and 45-degree horizontal bend, 3-inch center inlet/offset outlet mufflers, and adapters to transition from oval to round tubing with a 5-degree turn down and four-bolt collector flange. All this allows you to build an exhaust that is just 2-1/4 inches but flows like a full-on 3-inch system.

Granatelli Motor Sports also offers CNC-machined aluminum cutouts that have a smart chip-controlled activation switch to open and close the butterfly plates, stainless steel butterfly plates, and blade shafts. Kits are available for single- and dual-exhaust systems.
