Unobtanium C8 Z51 Titanium Cat Back Exhaust

The C8 Corvette Z51 is a great chassis, but the factory cat back is built around noise limits, cost and packaging more than sound quality or weight. The Unobtanium C8 Z51 Titanium Cat Back Exhaust replaces the OEM rear section with a lighter, freer flowing titanium system that lets the LT2 V8 feel a bit more responsive and gives it a more honest voice behind the cabin.

Each system is built from high grade titanium tubing with smooth bends and a clean flow path designed to reduce backpressure compared to the stock rear exhaust. It reuses factory style hangers and connections, so it bolts in without cutting or permanent changes to the car. The move to titanium also trims meaningful weight from the rear of the car and helps manage heat around the back of the engine bay.

Balanced sound for real world use

On start up and at idle you will notice a deeper, more purposeful tone. At part throttle and highway speeds there is more character than stock without being overly loud, and when you roll into the throttle the LT2 picks up a clearer, more aggressive note that suits a mid engine Corvette. It is designed to be engaging without feeling like a straight pipe every time you drive it.
