Drag Bike 201m Sunmori Exhaust Upgrade: What You Can Change

A Drag Bike 201m Sunmori exhaust upgrade is confirmed as a customization option: you can mix exhausts across the game’s bikes. However, the official description does not establish that changing an exhaust increases acceleration, top speed, or engine power. Treat exhaust swapping as a confirmed way to personalize your bike, not a documented performance upgrade.

What Exhaust Customization Includes

The official Google Play listing describes five drag bikes with interchangeable rims and exhausts. This supports building a bike with parts drawn from another bike rather than keeping every component matched to its original model.

The description also gives an underbone-style exhaust as an example of a customized build. It does not provide a named exhaust catalog, individual specifications, or a compatibility chart for every bike-and-pipe combination.

The important distinction is between swapping a component and upgrading its performance. Interchangeable exhausts are explicitly advertised; a progression system with stronger pipes, upgrade levels, or measurable horsepower gains is not described.

What Is Not Specified

The listing does not establish:

• Which exhaust, if any, produces the fastest 201-meter time.
• Whether exhaust changes affect torque, acceleration, weight, or maximum speed.
• Whether different pipes have distinct sounds.
• Whether exhausts require coins, ownership of another bike, or a separate unlock.
• The menu sequence or controls used to install an exhaust.

There is consequently no supported “best exhaust” ranking or exact installation walkthrough. An exhaust’s appearance alone is not enough to establish that it improves race results.

Building Around Your Exhaust Choice

Exhaust swapping belongs to a broader customization system. Alongside interchangeable rims, the game lets you change how much bodywork remains on a bike: a complete body, partial fairing, or a stripped configuration with the engine and frame exposed.

These options give an exhaust choice context. A pipe can be part of a stripped-back build or combined with more complete bodywork, rather than being the only visible modification. The listing does not assign performance bonuses to these bodywork configurations, so removing panels should not be presented as a confirmed weight-reduction upgrade.

Each bike also has two liveries, while the rider has helmet and jacket design options. Together, these features support personalizing the bike-and-rider combination. None of the listed appearance options comes with documented speed statistics.

Coins and Access to More Bikes

Completed races award coins. The official description states that winning gives the full reward, while finishing behind gives half. It also identifies buying new bikes as a use for saved coins.

That makes race completion relevant to expanding your collection, but it does not establish how exhaust access works. Buying another bike should not be described as a guaranteed exhaust-unlock step without further information. Likewise, there is no published exhaust price list or confirmed cost for swapping parts in the supplied listing.

For an exhaust-focused build, the supported progression facts are therefore limited: race finishes earn currency, currency can buy bikes, and the customization system allows cross-bike exhaust mixing. The exact relationship between bike ownership and available exhaust choices remains unspecified.

Exhaust Effects Versus Riding Physics

The game description mentions flames coming from the exhaust during backfires. This is a described visual effect, not evidence that a particular pipe provides extra power or a special boost.

By contrast, it explicitly connects rider inputs with bike behavior: applying too much throttle at the start can lift the front wheel, and excessive front braking can tip the bike forward. Those are documented handling effects; an exhaust-specific change to launch behavior is not.

The available riding formats include a standing-start 201-meter drag, an 800-meter drag, a road-racing circuit, and open-world sunmori riding. The open world also offers 400-meter street duels. These provide different settings for riding a customized bike, but the listing supplies no exhaust comparison results for any of them.

Bottom Line

Choose an exhaust for a personalized build with confidence that cross-bike exhaust customization is advertised. Do not assume it is a speed upgrade, spend coins based on an unsupported performance ranking, or mistake backfire flames for proof of higher output.

The store listing, marked updated November 11, 2026, supports the customization features described here but does not identify a numbered game version or publish exhaust performance data.
