The Akrapovic S-PO/TI/5H Slip-On Line in titanium with titanium tips is the benchmark exhaust upgrade for the 2016-2017 Porsche 911 Carrera S, 4, 4S, and GTS on the 991.2 platform. Built with precision-welded grade-1 titanium construction throughout, the S-PO/TI/5H drops significant weight from the rear of the 991.2 and transforms the flat-six's exhaust note into a sharper, more resonant sound that honors the 911's motorsport lineage. ECE approved for Carrera, Carrera S, Carrera 4, and Carrera 4S variants, this system is compatible with both coupe and cabriolet body styles and works seamlessly with the 991.2's factory sport exhaust valve system.

Frequently Asked Questions
Which 2016-2017 Porsche 911 991.2 variants does the S-PO/TI/5H fit?The S-PO/TI/5H fits the 2016 and 2017 Porsche 911 Carrera, Carrera S, Carrera 4, Carrera 4S, and Carrera GTS on the 991.2 platform, including both coupe and cabriolet body styles. It is specific to the 991.2 generation (introduced 2016) and is not compatible with the earlier 991.1 platform.
Does the S-PO/TI/5H work with the 991.2's factory sport exhaust valve system?Yes. The S-PO/TI/5H is engineered to interface with the factory sport exhaust valve system on the 991.2. The electronic valve and its driving mode sound programs continue to operate normally after installation, so the Normal, Sport, and Sport Plus mode sound behaviors are preserved and enhanced by the Akrapovic titanium construction.
What is the difference between titanium tips and carbon fiber tips on the 991.2 911?The S-PO/TI/5H includes titanium oval tips rather than carbon fiber tips. Titanium tips offer a brushed metallic finish that complements the 991.2's sport design language and, unlike carbon fiber, are not vulnerable to heat discoloration over prolonged use. The titanium tip aesthetic is more understated and suits owners who prefer the metallic look over the carbon fiber alternative available on other Akrapovic 911 system configurations.
Is the S-PO/TI/5H ECE approved for the 911 GTS?The ECE type approval covers the Carrera, Carrera S, Carrera 4, and Carrera 4S variants. The Carrera GTS is listed as a fitment application, but the ECE approval scope does not extend to the GTS variant. Buyers with 911 GTS models should verify local road use requirements applicable to non-type-approved exhaust modifications in their jurisdiction.
How does titanium compare to carbon fiber construction on an exhaust system?Titanium is the primary structural material of the S-PO/TI/5H muffler body. Grade-1 titanium provides exceptional strength at low weight, superior heat resistance, and inherent corrosion resistance, making it the premium choice for exhaust system construction. Carbon fiber is used for cosmetic components like end caps and tips on some Akrapovic systems, but the structural advantages of titanium in the muffler body are what deliver the significant weight reduction this system provides.
How much weight does the S-PO/TI/5H save over the factory 991.2 exhaust?The S-PO/TI/5H delivers measurable weight reduction compared to the factory stainless steel muffler assembly. Akrapovic's technical documentation specifies the exact weight saving for the 991.2 platform. Titanium's lower density versus stainless steel is the primary driver, and the weight reduction at the rear of the 911 contributes to improved rear-axle balance characteristics.
Will the S-PO/TI/5H fit the 2016-2017 911 Targa variants?The S-PO/TI/5H is specified for the Carrera, Carrera S, Carrera 4, Carrera 4S, and Carrera GTS. Akrapovic does not list the 991.2 Targa variants as confirmed fitment for this system. Buyers with Targa models should contact us to confirm fitment compatibility before ordering.
Is the S-PO/TI/5H street legal in California?The S-PO/TI/5H does not carry a CARB Executive Order number. While the system retains the factory catalytic converter and is not a decat product, it is not CARB certified for use in California on public roads. Buyers in California and other states that follow CARB emissions regulations should confirm local compliance requirements before purchasing this system.
