Titanium Valved Catback Exhaust System - Porsche 718 Cayman GT4 2020-2023

Upgrade the sound, performance character, and rear-end appearance of your Porsche 718 Cayman GT4 with this Titanium Valved Catback Exhaust System. Designed for enthusiasts seeking a lighter and more engaging exhaust setup, this system combines premium titanium construction with electronically controlled exhaust valves for adjustable sound characteristics.

The lightweight titanium tubing provides excellent resistance to heat and corrosion while producing the distinctive blue and purple heat coloration associated with high-performance titanium exhaust systems. Integrated exhaust valves allow the system to deliver a more restrained tone when desired and a louder, more aggressive flat-six exhaust note when the valves are opened.

Designed specifically around the exhaust layout of the Porsche 718 Cayman GT4, the system features performance-oriented routing, precision-welded sections, dual exhaust outlets, and mounting brackets for vehicle-specific integration.

Vehicle Fitment

• Porsche 718 Cayman GT4 - 2020-2023

Engine: Designed for compatible Porsche 718 Cayman GT4 models equipped with the naturally aspirated 4.0L flat-six engine.

Fitment Note: Please verify your exact model year, factory exhaust configuration, catalytic converter connections, rear diffuser, valve-control configuration, exhaust mounting points, and any existing aftermarket exhaust modifications before ordering.

GT4 RS Note: Compatibility with the Porsche 718 Cayman GT4 RS is not confirmed by the supplied product information and should be verified separately before purchase.

Performance & Sound

The freer-flowing titanium construction is designed to reduce unnecessary exhaust restriction and provide a more immediate, engaging exhaust character. The valve system allows the driver to change the exhaust volume depending on the driving environment.

Actual horsepower, torque, sound level, and weight savings can vary depending on the vehicle configuration, catalytic converters, headers, ECU calibration, and other exhaust modifications.

Installation

Professional installation by an experienced Porsche or performance exhaust specialist is strongly recommended. The complete system should be test-fitted before final tightening to verify exhaust-tip alignment, valve clearance, connection points, mounting brackets, and clearance from the rear diffuser and surrounding components.

Factory clamps, brackets, gaskets, valve wiring, or other components may need to be transferred depending on the vehicle configuration and the supplied kit.

After installation, operate the exhaust valves through their full range and confirm that all exhaust connections are properly sealed. Mounting hardware should be inspected again after the first complete heat cycle.

Road Use & Sound Compliance

Performance exhaust systems may increase exhaust volume and alter vehicle noise characteristics. Local road-use and sound regulations vary by location, so buyers should confirm applicable requirements before installation or use on public roads.

Production & Shipping

• Lead Time: 2 weeks
• Delivery: 1 week
• Returns: Allowed within 10 days after delivery
• Replacements: Only for items damaged on arrival

Care Guide

Allow Exhaust to Cool: Always allow the titanium exhaust system to cool completely before cleaning or performing maintenance. Exhaust components can remain extremely hot after driving.

Regular Cleaning: Clean exposed titanium surfaces using a soft microfiber cloth with mild automotive soap and water. Avoid aggressive abrasives or highly acidic cleaning chemicals.

Preserve Titanium Finish: Natural blue, purple, bronze, and gold discoloration may develop from heat exposure and is a normal characteristic of titanium exhaust systems.

Inspect Exhaust Valves: Periodically check valve mechanisms, actuators, wiring, and connections to ensure smooth operation and proper opening and closing.

Check Mounting Hardware: Inspect clamps, brackets, flanges, exhaust tips, and mounting hardware periodically, especially after track use or repeated high-temperature driving.
