Learn how the REMARK axleback exhaust transforms the sound of your 2018+ Crosstrek or 2017+ Impreza Wagon, plus fitment details and real-world driving impressions.

Quick answer

The REMARK axleback for the 2018+ Subaru Crosstrek and 2017+ Impreza Wagon adds a deeper, sportier exhaust note without being intrusive, and its HI-Tuck design improves ground clearance for light off-road use.

What the REMARK axleback sounds like

The REMARK axleback delivers a noticeable increase in volume over the stock exhaust, with a deeper tone that becomes more aggressive under throttle. At highway speeds, the cabin noise remains comfortable for daily driving. It avoids the drone that plagues some aftermarket exhausts, making it a solid choice for commuters who still want a sporty edge.

Fitment notes and considerations

This axleback is designed specifically for the 2018+ Subaru Crosstrek and 2017-2023 Impreza Wagon. The HI-Tuck design tucks the muffler closer to the chassis, giving extra clearance over rough terrain, gravel, or snow. Installation is straightforward as a direct bolt-on replacement for the stock axleback section, requiring basic hand tools and about 30-60 minutes.

Trade-offs to know

While the sound is more engaging, it is not a full cat-back system, so you won't see significant horsepower gains. The tone is also more noticeable during cold starts, which may be a consideration for early-morning neighbors. The increased clearance is beneficial for light off-roading, but the axleback alone does not change suspension or approach angles.

Frequently asked questions

Will the REMARK axleback fit my 2019 Subaru Crosstrek?: Yes, the REMARK axleback is designed for the 2018+ Subaru Crosstrek (including 2019) and 2017-2023 Impreza Wagon. It bolts directly to the factory mid-pipe.
How loud is the REMARK axleback compared to stock?: It is noticeably louder with a deeper tone, especially during acceleration. At highway speeds, the increase is moderate and does not cause drone. Cold starts are louder than stock.
Does the HI-Tuck design affect sound quality?: No, the HI-Tuck design primarily improves ground clearance by repositioning the muffler. The sound character is similar to a traditional axleback, with a sporty note that deepens under load.
Can I install this axleback myself?: Yes, it is a direct bolt-on replacement. You will need a jack, jack stands, a 12mm and 14mm socket, and penetrating oil for stubborn bolts. Expect 30-60 minutes. Check that your existing exhaust hangers are in good condition before starting.
Will this void my Subaru warranty?: The axleback is a cat-back component, so it generally does not affect the powertrain warranty. However, any modification can be subject to dealer discretion. Keep your stock parts to swap back if needed.
