Unobtanium C8 Z06 Titanium Cat Back Exhaust

Titanium cat back for the high revving LT6

The C8 Z06 already has one of the most interesting engines in a modern Corvette. A 5.5 liter flat plane LT6 that loves rpm deserves an exhaust that lets it breathe and actually sound the part. The Unobtanium C8 Z06 Titanium Cat Back Exhaust replaces the heavy factory rear section with a purpose built titanium system that cuts a significant amount of weight and reduces restriction compared to stock.

Unobtanium’s Z06 titanium cat back comes in at roughly 15.2 pounds, about one quarter of the mass of the OEM rear exhaust. That is a meaningful change at the very back of the car and helps the chassis feel a little more responsive while also lowering heat load around the rear of the engine. The layout is designed specifically for the Z06 platform and uses proper flanges and hangers so it bolts up cleanly in the factory locations without cutting or permanent modification.

Sound that suits the car

The goal with this system is not to turn the Z06 into a straight pipe, but to bring out more of the LT6 character. Compared to stock you can expect a crisper, more engaging tone that builds with rpm, with more presence on start up and under load. At cruise it settles into a refined background note that still works on real roads. Final volume and any potential resonance will depend on the rest of the exhaust and your overall setup.

• Titanium cat back exhaust for the C8 Corvette Z06
• Approximate system weight of 15.2 lb, around one quarter of the factory rear exhaust assembly
• Engineered specifically for the LT6 Z06 application with factory style mounting points
• Significant weight reduction at the rear of the car along with reduced backpressure compared to the OEM rear section
