Akrapovic Evolution Line Review: 2016-2017 BMW M2 (F87)

The Akrapovic Evolution Line titanium cat-back is the definitive exhaust upgrade for the 2016–2017 BMW M2 (F87), and this review breaks down exactly what the $7,841.63 system delivers on the N55-powered base car. Hand-built from ultra-lightweight titanium with carbon-fiber tips, the Evolution Line (part number ME-BM/T/8H) is a full downpipe-back replacement that transforms the F87's voice, sheds weight from behind the rear axle, and sharpens throttle response — without the drone that plagues cheaper systems. Here is our complete verdict after living with the car and the part in our Tampa, FL shop.

What Is the Akrapovic Evolution Line for the BMW M2?

The Akrapovic Evolution Line is a full titanium cat-back exhaust system designed specifically for the 2016–2017 BMW M2 (F87) with the N55 engine, excluding the later M2 Competition. Unlike a slip-on, which only swaps the rear muffler, the Evolution Line replaces the exhaust from the downpipe back with a completely re-engineered path. Where the factory M2 uses a single-tube layout, Akrapovic runs two separate titanium tubes from the connecting pipe to the muffler, shaped for optimum gas flow and a fuller sound.

Akrapovic is the Slovenian manufacturer that supplies exhausts to MotoGP, WRC, and multiple manufacturer motorsport programs, and the Evolution Line is its top consumer tier. Every system is hand-welded from aerospace-grade titanium, finished with genuine carbon-fiber tailpipe tips, and ECE type-approved for road use in most markets. For the F87 M2, this is the same construction philosophy Akrapovic applies to six-figure supercars, adapted to the N55.

The 2016-2017 BMW M2 (F87): What You Are Working With

The first-generation BMW M2 (F87) launched for 2016 with the N55B30 — a 3.0-liter single-turbo inline-six making 365 hp at 6,500 rpm and 343 lb-ft of torque from 1,400 rpm, with an overboost function on manual cars. That is enough to push the roughly 3,450 lb coupe from 0–60 mph in about 4.1 seconds with the six-speed manual (4.2 seconds with the seven-speed DCT), on to an electronically limited 155 mph. It is the last M2 to use the N55, as the 2018+ Competition switched to the twin-turbo S55.

The N55 is torque-rich but acoustically muted from the factory, with an active exhaust flap that BMW keeps conservative. That is precisely why the exhaust is the single most transformative bolt-on for this car: the engine is already boosted and eager, so a free-flowing titanium system unlocks the character BMW muffled for the showroom. The Akrapovic Evolution Line is built to exploit exactly that.

How Much Weight Does the Titanium System Save?

Titanium is the headline. Grade-for-grade, titanium is roughly 40% lighter than the stainless steel BMW uses for the factory M2 exhaust, so the Evolution Line strips meaningful mass from the very back of the car — the worst place to carry weight for a coupe that lives on turn-in and rotation. On the closely related F87 platform, Akrapovic quotes weight savings of up to 17.4 kg (about 38 lb) for its Evolution Line system versus stock, and the base-car cat-back is built the same way from the same materials.

In the real world, that dropped weight sits behind the rear axle and low in the chassis, so the M2 feels noticeably more willing to change direction and settles faster over bumps mid-corner. It is the kind of upgrade you feel in the steering long before you see it on a dyno — and it is unsprung, rotational-adjacent mass you cannot claw back with a tune alone.

What Does the Akrapovic M2 Exhaust Sound Like?

The Akrapovic F87 M2 exhaust produces a deeper, higher-frequency race tone up top while staying refined and drone-free at cruise. Akrapovic's sound engineers voiced the Evolution Line to give the N55 inline-six a muscular, almost muscle-car growl at low rpm that hardens into a genuine racing wail near the 7,000 rpm redline. Crucially, the twin-tube geometry and tuned muffler were designed to eliminate the resonant highway drone that makes many budget cat-backs unlivable on a daily driver.

On the base M2, the factory sound is polite and partly synthesized through the speakers; the Evolution Line makes it honest. Cold starts get a hard titanium bark, part-throttle around town gains presence without booming, and full throttle finally lets the N55 breathe with the intensity the chassis has always deserved. Pair it with the Akrapovic Sound Kit if you want additional control over the exhaust valve behavior.

Does the Evolution Line Add Horsepower on the N55?

A cat-back exhaust delivers modest power on its own; the biggest gains on the N55 come when it is paired with a downpipe and a tune. As a downpipe-back system, the Evolution Line lowers backpressure and improves flow versus the restrictive factory muffler, which is worth a few horsepower and a crisper throttle on a stock N55. For reference, Akrapovic quotes gains of up to 14.8 kW (about 20 hp) and 29.8 Nm (about 22 lb-ft) at specific rpm points for its Evolution Line on the related F87 M2 — figures that scale with supporting mods.

Our honest take: buy the Evolution Line for the sound, the titanium weight loss, the throttle response, and the jewelry-grade build — not for a dyno headline. If peak numbers are your priority, budget for a catless or high-flow downpipe and an ECU tune, and let the Akrapovic be the free-flowing back half of that package. On a base M2, the exhaust is where the emotional return on investment is highest.

Base M2 vs. M2 Competition: Will This Fit My Car?

This system fits only the 2016–2017 base BMW M2 (F87) with the N55 engine — it does not fit the 2018+ M2 Competition or M2 CS, which use the twin-turbo S55 and a different exhaust architecture. Before ordering, confirm your car is the base M2: N55 cars were built for the 2016 and 2017 model years before the Competition arrived. If you run the S55 Competition, you need Akrapovic's dedicated Competition slip-on instead.

Below is how the Evolution Line cat-back stacks up against the other genuine Akrapovic pieces we stock for the base F87 M2, so you can build the exact package you want — from a full system to a sound-only upgrade or a carbon rear finish.

Installation: What to Expect

The Evolution Line is a direct bolt-on cat-back that installs in roughly two to three hours on a lift with no cutting or welding. It mounts to the factory hangers and connecting-pipe flange, so a competent shop — or a confident DIYer with a lift and basic hand tools — can fit it in an afternoon. Because it is a heavy, freight-shipped titanium system, we recommend a professional install to guarantee correct alignment of the twin tips in the rear valance.

At NLP Performance in Tampa, FL, we install Akrapovic systems regularly and torque every flange to spec so the tips sit dead-level in the diffuser. If you are adding a downpipe at the same time, do both jobs together to save labor and get the full N55 power picture in one dyno session.

Is the Akrapovic Evolution Line Worth $7,841?

The Akrapovic Evolution Line is worth it if you value hand-built titanium quality, a motorsport pedigree, and the best factory-beating sound available for the F87 M2 — it is a lifetime-grade part, not a value play. At $7,841.63 it costs two to three times what a stainless steel cat-back from a mainstream brand runs, and the raw power difference between them on a stock N55 is small. What you are paying for is the metallurgy, the acoustics, and the resale-friendly badge: a genuine Akrapovic titanium system holds its desirability far better than a no-name muffler.

For a garaged, well-kept base M2 that its owner intends to keep, the Evolution Line is the exhaust to buy once and never second-guess. Shoppers chasing the lowest cost-per-horsepower should look at a downpipe-and-tune package first, since that is where the N55 makes its biggest gains. But if the goal is to own the definitive version of the first-generation M2 — lighter, louder in the right way, and finished like a supercar — the Akrapovic earns its price. In our Tampa shop, it is the single upgrade owners regret the least.
