Learn what to expect from the REMARK R1 Dual Canisters axleback on a Subaru WRX VB, including tone, volume, and installation tips for the best sound.

Quick answer

The REMARK R1 Dual Canisters axleback delivers a deep, aggressive exhaust note on the Subaru WRX VB, with manageable volume thanks to the straight-through 2.5-inch mufflers.

What influences the sound profile

The R1 Dual Canisters use straight-through 2.5-inch inner diameter muffler canisters. This design suppresses harsh frequencies while keeping a deep tone, making the exhaust louder than stock but not overwhelming. The outward-angled 4-inch slant cut tips also project sound differently than straight tips, giving the WRX VB a more aggressive presence from the rear.

Trade-off: volume vs. tone

Because this is an axleback kit, it bolts directly to the stock midpipe. That means the sound is noticeably louder than stock, but still more controlled than a full catback. If you want a deeper, less raspy tone, consider pairing it with a REMARK midpipe kit later—but the axleback alone already gives a satisfying growl without excessive cabin drone.

Steps to get the best sound from your R1 Dual Canisters

Install the axleback securely: Bolt the R1 kit directly to the OEM midpipe using the supplied hardware. Tighten all clamps evenly to prevent exhaust leaks that can cause a tinny or uneven tone. Check for leaks after first start—listen for hissing at the joint.
Let the exhaust break in: Drive for about 100–150 miles before judging the final sound. Fresh muffler packing and metal will settle, deepening the tone slightly and reducing any initial sharpness. The note will mellow and become fuller after break-in.
Pair with a midpipe for more volume: If you want a louder, more aggressive note, add a REMARK midpipe kit later. This creates a full catback system and removes the stock muffler’s restriction, increasing both volume and depth. A midpipe upgrade alters the sound significantly—plan your final setup before committing.
