TNEER Valvetronic Exhaust System for Ferrari California T 2015-2017
The Ferrari California T marked a significant transition in Ferrari's grand touring lineup, replacing the naturally aspirated 4.3-litre V8 of the original California with a turbocharged 3.9-litre V8 producing 560 horsepower. It was Ferrari's first turbocharged road car in over two decades, and the platform that established the forced-induction V8 architecture that has defined Ferrari's entry-level grand touring range ever since. The front-engine, retractable hardtop convertible configuration creates exhaust routing requirements specific to the California T, with longer primary runs through the transmission tunnel and underbody and packaging constraints introduced by both the front-engine layout and the folding roof mechanism. TNEER engineers this valvetronic system specifically for the California T, with tube routing and mounting geometry developed to the exact chassis layout of the platform.
Each section is formed from single-piece high-grade stainless-steel tubing using robotic pipe bending technology, producing continuous tube geometry throughout the system without the weld joints and flow disruptions of multi-segment construction. On a front-engine forced-induction platform with extended underbody runs, maintaining consistent internal diameter and precise routing geometry is particularly consequential to exhaust gas velocity and turbocharger efficiency under sustained load. The system installs to all factory mounting locations, requiring no structural modification and maintaining correct chassis alignment throughout.
The valvetronic rear mufflers are controlled directly from the car's cabin. Valves closed, the system maintains a composed, refined tone consistent with the California T's grand touring character while presenting more of the turbocharged V8's acoustic presence than the factory exhaust allows at any throttle position. Valves open, the full acoustic output of the California T's V8 is unobstructed and responds directly to throttle input and engine speed. In open-top configuration, the exhaust note is experienced without the attenuation of roof structure or cabin insulation, making the distinction between valves closed and valves open particularly immediate.
Optional System Configurations
The valvetronic rear muffler system delivers a meaningful improvement over the factory exhaust as a standalone upgrade. For owners who want to address the complete exhaust path, TNEER offers a mid X-pipe and two downpipe specifications that extend the system from the rear mufflers back to the primary collection points.
- The mid X-pipe cross-links both exhaust banks at the mid-system junction, balancing pulse energy between the V8's cylinder banks. On a twin-turbocharged platform, cross-pipe scavenging at the mid-system contributes to exhaust flow efficiency and tonal coherence across the rev range, allowing the full character of the California T's V8 to express itself consistently through the system under all operating conditions.
- The race downpipes remove the factory catalytic converters immediately downstream of the turbocharger outlets, where back pressure reduction has the most direct effect on turbine behavior, spool characteristics, and mid-range torque delivery. These components are intended for closed course and off-road use.
- The 200-cell sport downpipes retain a high-flow catalytic substrate in place of the factory units, reducing restriction significantly while maintaining a level of emissions compliance appropriate for street-driven builds. For California T owners who require a balance between full-system performance and the car's daily grand touring operating profile, the 200-cell specification delivers a substantive upgrade within a practical context.
All optional components are fabricated from high-grade stainless steel and engineered to the same fitment standard as the valvetronic rear muffler system.
About TNEER:
TNEER is built around a single engineering conviction: the exhaust system is not a peripheral component. It is the primary interface between the engine and the driver's experience of it. Every system TNEER produces is developed to bring out the true voice of the engine it is built for, improving exhaust flow and delivering a distinct tone that is mechanical, raw, and directly connected to the character of the car.
The manufacturing process that defines TNEER's fitment standard is their high-tech robotic pipe bending technology. Rather than fabricating exhaust routing from multiple welded sections, TNEER forms each tube from a single continuous piece, bending high-grade material to navigate the spatial constraints of each specific engine bay without the diameter reductions, flow disruptions, and structural inconsistencies that welded multi-piece construction introduces. The result is an exhaust system with continuous tube geometry, perfect fitment to the platform it is built for, and no compromises in the routing that precision bending makes unnecessary.
For enthusiasts who regard sound and performance as inseparable elements of the driving experience, TNEER engineers each system to deliver both from the first throttle input.
Note:
- Downpipes are not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only.
-
ECU tuning may be required due to removal of factory catalytic converters.
