Akrapovic G80 M3 Exhaust: Titanium Slip-On Systems

The Akrapovic G80 M3 exhaust range is the most complete titanium upgrade path available for the current twin-turbo M3, and at NLP Performance we stock the full lineup for the S58-powered car. Akrapovic engineered these systems specifically around the 3.0-liter inline-six biturbo (S58) that powers the G80 BMW M3 (2021 and newer), including the M3 Competition and M3 Competition xDrive, with shared fitment across the closely related G82 M4 and G87 M2. Whether you want the flagship Slip-On Line with carbon tips, a tip-only refresh, a resonator-delete link pipe, or the Sound Kit for valve control, every component here is built from aerospace-grade titanium and carbon fiber and engineered to bolt onto the S58 without a tune.

What Akrapovic offers for the G80 M3

Akrapovic builds a layered system for the G80 chassis so owners can choose how far they want to go. At the top sits the Slip-On Line (Titanium) with Carbon Tips — the complete rear-section exhaust delivered with finished tailpipes in the box. For buyers who already own a preferred set of tips, or who want to mix-and-match the octagonal versus classic look, Akrapovic also sells the same Slip-On muffler in a "Req. Tips" configuration that leaves the tip choice open. Below that are the modular pieces: the Evolution Short Link pipe (without resonator) for owners chasing a louder, more aggressive note, two carbon tail pipe sets, the Sound Kit for electronic valve control, and the OPF/GPF Fitting Kit required on particulate-filter cars. Together they cover everything from a subtle factory-plus upgrade to a track-focused build.

The flagship: Slip-On Line (Titanium) — material, tips, construction

The Slip-On Line is Akrapovic's entry into the brand's exhaust hierarchy, and on the G80 it is the most popular choice for good reason. It replaces the factory rear section — the mufflers and tailpipes — while the catalytic converters and mid-pipe stay in place, which keeps installation straightforward and preserves the car's emissions hardware. The full system is built from high-grade lightweight titanium and finished with hand-crafted carbon-fiber tailpipes, while a pair of collectors is cast in Akrapovic's own in-house foundry. The headline version we recommend is the Slip-On Line (Titanium) with Carbon Tips, which arrives complete and ready to install. If you prefer to select your tips separately, the same muffler is offered in two "Req. Tips" SKUs at a lower entry price, leaving the tail pipe set as a standalone decision.

Akrapovic offers the tailpipes in two distinct shapes. The newer octagonal design merges modern angular geometry with titanium's light, resilient structure under a carbon-fiber outer sleeve, while the classic cylindrical design caters to traditionalists who want a cleaner round tip. Both are available as dedicated tail pipe sets so owners running a "Req. Tips" Slip-On can finish the system exactly how they like.

Tail pipe sets & tips

For G80 owners running a "Req. Tips" Slip-On muffler — or anyone who simply wants to swap their look — Akrapovic sells the carbon tail pipe sets on their own. The Octagonal Carbon Design Tail Pipe Set brings the bold, angular geometry that defines the latest Akrapovic look, while the Classic Carbon Design Tail Pipe Set keeps the round, understated profile. Both are carbon-fiber over titanium and share fitment across the G87 M2, G80 M3, and G82 M4, so they are a clean way to personalize the rear of the car or replace tips that have weathered.

The Evolution Short Link pipe & sound control

Owners who want a more aggressive character can add the Evolution Short Link pipe (without resonator). Built from titanium, this resonator-delete link pipe removes a restriction in the flow path and frees up a noticeably harder, more vocal note from the S58 — the kind of upgrade that takes the Slip-On from refined to unmistakably purposeful. It is the natural step for a build that prioritizes sound and presence over absolute quietness.

For drivers who would rather dial the volume up and down on demand, the Akrapovic Sound Kit (part P-HF1384) provides manual control of the exhaust valves. With it you can keep things discreet on an early-morning commute, then open everything up for a back-road run. It is worth noting that fitting the Sound Kit voids the system's ECE type approval, so it is best understood as a track-and-spirited-road accessory rather than a homologated street part.

Weight savings & materials

Weight is where the Slip-On Line earns its keep. Akrapovic states the titanium system is roughly 35 percent lighter than the stock rear exhaust, a meaningful reduction in unsprung and rear-of-car mass on a machine where every kilogram at the tail matters for balance. Titanium delivers that saving while retaining the heat tolerance and durability a turbocharged exhaust demands, and the carbon-fiber tailpipes add visual contrast without adding weight. The in-house-cast collectors keep flow smooth where the system meets the factory mid-pipe, so the lighter build does not come at the expense of consistency. For a daily-driven track car, that combination of reduced mass and premium materials is exactly what separates an Akrapovic system from a heavier stainless aftermarket muffler.

Sound & performance: what to expect

On the dyno, Akrapovic measured the Slip-On Line at 8.0 kW (10.9 hp) at 6,000 rpm and 13.9 Nm of extra torque at 5,000 rpm when tested against a BMW M4 Competition running the standard stock exhaust — and crucially, those gains are achieved with no remapping necessary. The S58 responds well to reduced backpressure, and while the gains are modest in isolation, they arrive alongside a sharper throttle response and a far more characterful soundtrack. The Slip-On alone delivers a deeper, richer tone than stock; add the resonator-delete Evolution link pipe and the car takes on a genuinely hard edge, while the Sound Kit lets you choose your moment. This is a system that flatters the engine's natural voice rather than masking it in drone.

Fitment: years, engine code & variants

These systems are engineered for the G80 BMW M3 from 2021 onward, powered by the S58 3.0-liter twin-turbo inline-six. The Slip-On Line, tail pipe sets, Sound Kit, and Evolution link pipe carry shared fitment across the G87 M2, G80 M3, and G82 M4 — this is correct and expected, as the three cars share the same rear-exhaust architecture. The M3 Competition and M3 Competition xDrive both run the S58 and are covered by the same parts. The OPF/GPF Fitting Kit is the one item with a tighter window, listed for the 2021–2022 M3 (G80) on particulate-filter cars, so always confirm whether your specific car is OPF-equipped before ordering. If you are unsure, the team at NLP Performance can help you match the right combination to your exact build.

Installation & what's required

Because the Slip-On Line replaces only the rear section, installation is among the simplest of any Akrapovic system — a skilled technician can typically complete it in a couple of hours with minimal cutting or welding. Two points are worth planning for. First, the "Req. Tips" versions of the Slip-On do not include tailpipes, so you must pair them with one of the carbon tail pipe sets (octagonal or classic); the all-in-one Slip-On with Carbon Tips avoids that extra step. Second, G80 cars fitted with an Otto/gasoline particulate filter require the OPF/GPF Fitting Kit for a proper, leak-free installation. Budget for these companion parts up front so your install goes in clean the first time.
