Akrapovic 997 Turbo Exhaust: 997.2 Turbo/S Titanium Slip-On

The Akrapovic 997 Turbo exhaust program is one of the most thoroughly engineered titanium systems Akrapovic has ever built for a Porsche, and it remains the benchmark upgrade for owners of the second-generation 997. This article covers the Akrapovic hardware available right now for the facelift 997.2 chassis — the 2010–2013 Porsche 911 Turbo and Turbo S (997 FL), powered by the direct-injection 3.8-liter twin-turbo flat-six. At its center is the flagship Slip-On Line in titanium with titanium tips, supported by a family of genuine Akrapovic mounting brackets and fitting kits drawn from the 997 platform. Below we break down the construction, the weight savings, the sound character, and exactly what fits.

What Akrapovic Offers for the 997.2 Turbo

For the 997.2 Turbo and Turbo S, Akrapovic's headline product is the Slip-On Line (Titanium) with titanium tips. A Slip-On is the entry point into the Akrapovic catalog in the best sense of the term: it replaces the rear section of the factory exhaust — the center muffler and the tailpipes — while leaving the catalytic converters and the engine's emissions hardware in place. That design choice is exactly why it remains street-friendly, why it bolts on without an ECU remap, and why it is the natural first modification for a Turbo owner.

Surrounding the flagship are several pieces of authentic Akrapovic install hardware from the 997 family — side muffler and header bracket assemblies plus fitting kits. These are the support parts that secure an Akrapovic system to the chassis and replace mounting components consumed during installation. They are not exhausts in their own right; think of them as the genuine OEM-grade mounting and fitting hardware that keeps a titanium system properly located and rattle-free.

The Flagship: Slip-On Line — Material, Tips, Construction

The 997.2 Turbo Slip-On Line is built around a very lightweight center muffler crafted from Akrapovic's proprietary titanium alloy, paired with a set of unique tailpipes. The version offered here is the titanium-tip configuration, so the exit tips match the muffler material rather than relying on a separate carbon-fiber tip set. Titanium is the heart of the Akrapovic philosophy: it is dramatically lighter than the stainless steel a factory system uses, it tolerates extreme exhaust-gas temperatures, and it carries the distinctive bluish heat patina that telegraphs the system's pedigree the moment you look under the rear bumper.

Construction is where Akrapovic separates itself from generic aftermarket cans. Every weld, bend, and cone is optimized for flow, and the muffler internals are tuned to suppress the harsh resonance — the highway drone — that plagues cheaper systems. The result is a rear section that is lighter, freer-flowing, and acoustically engineered, not simply hollowed out for volume.

Slip-On vs Evolution vs Race Line: Where This System Sits

Akrapovic organizes its car exhausts into tiers, and understanding them clarifies why the Slip-On is the right call for a road-driven 997.2 Turbo. The Slip-On Line replaces only the rear muffler section and retains the factory catalytic converters, keeping the car emissions-compliant and quiet enough for daily use. The Evolution Line goes further, replacing a much larger portion of the system — typically from the catalytic converters back — with headers and link pipes built entirely from titanium. The Race Line shares the Evolution's geometry but is constructed in stainless steel and is aimed squarely at track and competition use.

For the overwhelming majority of 997.2 Turbo owners, the Slip-On Line is the sweet spot: titanium weight savings and the signature Akrapovic voice, without sacrificing street legality or requiring tuning. The deeper-replacement lines exist for owners chasing maximum airflow on dedicated builds.

Weight Savings & Materials

Weight is the headline benefit of any titanium Akrapovic system. Across the Porsche 911 Turbo family, an Akrapovic titanium Slip-On strips a large fraction of the factory rear section's mass — comparable systems on the platform deliver weight reductions well in excess of a third over the stock exhaust. That mass comes off the very back of the car, where it has an outsized effect on rotational balance and how the rear axle behaves through transitions. Less weight hanging behind the rear wheels sharpens the Turbo's responses and meaningfully improves its power-to-weight ratio.

Beyond the scale, titanium changes the thermal picture. It handles searing exhaust temperatures better than steel and helps reduce underbody heat soak, which is exactly the kind of detail that matters on a forced-induction flat-six working hard. At NLP Performance, this combination of lower mass and better heat management is why we steer 997.2 Turbo owners toward the titanium Slip-On rather than a heavier stainless alternative.

Sound & Performance: What to Expect

Akrapovic's sound engineers tuned the 997.2 Turbo system to deliver a deep, sporty, higher-frequency note — closer to a muscle-car bark than the muted factory tone — while keeping it smooth and eliminating the drone that ruins long drives. The character is aggressive when you ask for it and civilized when you do not, so the car stays usable on the daily commute and turns into something visceral under load. The turbocharged flat-six gains a richer, more resonant voice that finally matches the car's performance.

On the performance side, the freer-flowing titanium rear section helps the engine breathe more easily on the exhaust stroke. Akrapovic positions the Slip-On as a system that improves power and torque while dramatically lightening the rear of the car. We do not publish dyno figures we cannot verify for this exact application, but the consistent story across the Turbo lineup is a meaningful, felt improvement in throttle response and mid-range pull, layered on top of the substantial weight reduction.

Sound Control & Valve Behavior

The 997.2 Turbo Slip-On is compatible with the Akrapovic Sound Kit, which controls the valves inside the exhaust and lets the driver switch between sound modes. With valve control in play, the system can stay relatively reserved for cold starts and cruising, then open up for a louder, more theatrical character when the road opens up. That flexibility is part of why the Slip-On suits owners who use their 997.2 Turbo as more than a weekend toy — it adapts to the moment instead of committing you to one volume.

Fitment: Exact Years, Engine, and Variants

The flagship Slip-On Line (Titanium) is engineered specifically for the facelift 997 — the 997.2 chassis — covering the 2010–2013 Porsche 911 Turbo and Turbo S with the direct-injection 3.8-liter twin-turbo flat-six. The "997 FL" designation in the product name marks it as the facelift car, which is the only Turbo generation this particular muffler is designed to fit. If your car is a pre-facelift 997.1 Turbo, this is not the correct system; the part numbers differ across the facelift boundary.

The supporting bracket assemblies and fitting kits in this lineup are sourced from the broader 997 program (the GT3/RS-type 997 hardware) and serve as genuine Akrapovic mounting and fitting components. Always confirm the exact bracket or kit against your specific build before ordering, and reach out to our team if you are unsure which fitting hardware your installation requires.

Installation & Required Hardware

Because the Slip-On Line replaces only the rear section, installation is straightforward relative to a full system — it is a bolt-on swap that retains the factory catalytic converters and needs no ECU remap. That said, a proper install benefits from genuine Akrapovic mounting and fitting hardware. The bracket assemblies and fitting kits below are the supporting components that secure the system and replace the mounting parts disturbed during the swap. We recommend having the correct fitting kit on hand before the install so the job is done once and done right.
