Mercedes-Benz A200 W177: waking up the 1.3 turbo, the exhaust guide

Your vehicle.

All our exhausts for this generation, version by version, are brought together on one page: Mercedes A-Class W177 exhaust system.

Launched in spring 2018, the fourth generation of the A-Class, code W177, marked a real change of category for Mercedes-Benz's compact: an interior inspired by higher-end models, large screens and the voice-controlled MBUX multimedia system, inaugurated on this car. The A200 is one of the most common petrol versions, powered by a small-displacement supercharged four-cylinder. It targets customers who want an elegant, pleasant and economical compact, without seeking the performance of the AMG versions, but who appreciate a lively and well-finished car, as comfortable in the narrow streets of a city centre as on a fast road. That is precisely why its factory exhaust was tuned to be forgotten: you hear almost nothing of the engine, either on board or from the pavement.

The A-Class W177 and its engine range

The A-Class W177 comes in many versions, from the economical diesel to the most powerful AMG models. In this range, the A200 holds a central place: powerful enough for dynamic driving, economical enough for everyday use, and offered with a wide choice of equipment and trim lines. You see it as often in entry-level form as with the AMG Line, whose sportier bumpers give it a more assertive look.

It must be clearly distinguished from the AMG versions of the same generation. The A35 and A45 W177 get a far more powerful 2.0-litre, all-wheel drive and an entirely different exhaust line. At Rog, they have their own product pages and their own guides, with options that do not concern the A200. The line presented here is designed for the A200's small four-cylinder, and for it alone.

The M282, a 1.3-litre turbo

The M282 is a 1.3-litre four-cylinder with direct injection and a turbocharger, with an aluminium block. In the A200, it delivers 163 hp and 250 Nm, a torque available very early in the revs, which makes the car lively off the line and pleasant in town. Its small displacement and turbocharging let it combine good economy with respectable performance for a compact of this weight.

This type of engine naturally has a lighter voice than a 2.0-litre or a six-cylinder: a fairly high-pitched purr at idle, which becomes raspier when you pick up speed again. It is precisely this character that the factory line almost entirely erases, and that the Rog cat-back brings out.

Manual or dual-clutch gearbox

Depending on market and model year, the A200 was offered with a six-speed manual gearbox or with the 7G-DCT, a seven-speed dual-clutch automatic transmission. In Europe, most cars sold got the latter, which changes gear smoothly and favours relaxed driving.

The Rog line does not depend on the gearbox: it connects behind the catalytic converter, with the same geometry in every case. Your VIN tells us the exact configuration of your car, including its body, before manufacturing begins.

The model years covered and the 2023 facelift

The Rog product page is drawn up for the A200 W177 of model years 2019 to 2021, the period when this model sold best with the M282 in its original form. The very first cars, delivered as early as 2018, are very close to it, but we prefer to check their VIN before launching manufacturing rather than assume.

In 2023, the A-Class W177 received a mid-life facelift: reworked front end and lights, updated interior and, for the petrol engines, 48-volt mild-hybrid electrification. These recent cars fall outside the range of the product page. If your A200 dates from 2022 or later, send us its VIN: we will reply in writing with the line that suits it.

A small engine you don't hear as standard

Mercedes-Benz tuned the A200's exhaust for comfort above all. The factory silencers filter almost all of the M282's pulses, and the careful sound insulation of the cabin does the rest: at a steady speed, the engine is forgotten, and even under full acceleration you hardly hear more than a distant breath. That is pleasant for everyday use, much less so for those who expect a bit of character from their car.

On an engine of this size, the exhaust makes almost all of the sound character. With the flaps open, the Rog line gives the A200 a start-up you can hear, a livelier and deeper voice when you pick up speed again, and a more present grain as the revs climb, without anything intrusive. With the flaps closed, the gases pass through the silencers and the compact returns to a sound level close to standard.

The Rog remote to choose the moment

The line's flaps arrive fitted, with their remote: this is the "Rog" option on the product page. One button opens them, the other closes them, and they keep that position until your next command, whatever driving programme is engaged. The unit is stored in the boot.

This operation suits a car like the A200 well: flaps closed for everyday trips, early departures or long motorway stages, open for a winding road or a weekend outing. Nothing changes in the engine management or in the on-board equipment.

A line only, no front section

This product page offers no part upstream: the Rog line connects behind the factory catalytic converter, which stays in place and keeps treating the gases as before. No remap is therefore needed, and the 163 hp and 250 Nm quoted by Mercedes-Benz remain those of your car.

This choice also simplifies fitting: your garage removes the old rear section and puts the Rog line in place with clamps and gaskets, with no welding or cutting, in about two hours. The operation is reversible, and the original line can be kept.

Stainless steel or titanium for a compact

304 stainless steel suits a car driven all year round, in the rain as on salted roads in winter; it gives the A200 a full, round voice. Titanium, about 40% lighter for the same design, brings a slightly clearer note in the revs and comes in three shades: brushed, gold or purple.

Whatever the material, the line is made in 20 working days to your VIN, delivered free of charge and covered by a 3-year warranty. It arrives ready to fit, with the flaps fitted and the remote.

How the exhaust is put together

On the A200 W177, the Rog line starts at the flange behind the factory catalytic converter and runs to the rear of the car, with the silencers and the flaps. No upstream part is offered for this version: the standard catalytic converter stays in place.

Each choice explained in detail, from sound to material: How to configure your exhaust.

Three recommended configurations.

• Everyday compact

  • A200
  • 304 stainless steel
  • Rog remote

  For an A200 that does the commute every day: a livelier voice when you open the flaps, the standard calm when you close them, and a stainless steel that fears neither rain nor salt.
