Akrapovic 2018 Porsche GT3 RS (991.2) Slip-On Line (Titanium) (Req. Tips)

The Akrapovic S-PO/TI/10H Slip-On Line is purpose-built for the 2018 to 2019 Porsche 911 GT3 RS in the 991.2 generation, delivering a verified 6 kW of additional power at 8,250 rpm and 8 Nm of torque at 5,900 rpm from a bolt-on titanium muffler replacement. The system weighs just 12.4 kg, removing 15.8 kg from the rear of the car compared to the OEM system. High-grade titanium and Inconel construction handle the GT3 RS’s high-revving 4.0L flat-six thermal loads with precision. The S-PO/TI/10H produces an Akrapovic-characteristic deep and resonant tone that intensifies toward the 9,000 rpm limit without sounding strained. Note: exhaust tips (Akrapovic T-PO/13T) are sold separately and are required to complete the installation.

Frequently Asked Questions

Does the Akrapovic S-PO/TI/10H fit both the 2018-2019 GT3 and GT3 RS?

Yes. The S-PO/TI/10H Slip-On Line is confirmed for both the 2018-2019 Porsche 911 GT3 and 911 GT3 RS in the 991.2 generation. Both models use the naturally aspirated 4.0L flat-six and share the same rear muffler mounting configuration.

What tips are needed for the S-PO/TI/10H?

The S-PO/TI/10H muffler ships without exhaust tips. You must order the Akrapovic titanium tip set T-PO/13T separately to complete the installation. The tips are available as an add-on from Black Ops Auto Works.

How much power does the Akrapovic S-PO/TI/10H add to the 991.2 GT3 RS?

Akrapovic’s dyno results on the 991.2 GT3 RS show a gain of 6 kW at 8,250 rpm and 8 Nm of additional torque at 5,900 rpm. This is particularly meaningful on a naturally aspirated engine where every available horsepower in the upper rev range contributes to lap time.

How much weight does this exhaust system remove?

The S-PO/TI/10H reduces exhaust system weight by 15.8 kg over the factory unit. The system itself weighs 12.4 kg. This reduction in rear mass improves weight distribution and directly benefits cornering balance and acceleration from slower corners.

Is the S-PO/TI/10H difficult to install?

The system is a direct bolt-on replacement requiring no cutting, welding, or chassis modification. However, given the cost of the system and the precision required for proper tip alignment, professional installation at an experienced Porsche or performance exhaust shop is strongly recommended.

What does the GT3 RS sound like with the Akrapovic S-PO/TI/10H?

The exhaust note is deeper and more aggressive than stock across the entire rpm range, with a dramatic buildup toward the 9,000 rpm redline. At light throttle the sound is refined and does not produce cabin drone. At wide-open throttle the naturally aspirated flat-six produces an unmistakable, high-revving character that is more reminiscent of a factory race car than a street vehicle.

Does this system require any ECU remapping?

No. The S-PO/TI/10H is a muffler-only slip-on system that does not modify the headers, catalytic converters, or primary piping. No ECU remapping is required for installation.

What is the warranty on the Akrapovic S-PO/TI/10H?

Akrapovic covers this system with a 3-year manufacturer warranty against defects in materials and workmanship under normal street and occasional track use conditions.
