TODOROKI™ SINGLE Made-to-Order Single-Exit Exhaust｜BMW M240i G42 (B58)

The B58 is a 3.0L straight-six single-turbo. Fitted to the M240i G42, and despite not being an M model,Threatens M-level torque in the everyday range. It combines boost that builds from low revs with the natural smoothness of a straight-six. Set against that, the factory exhaust is plainly short on sound pressure.

TODOROKI™ SINGLE takes everything from the catalytic converter back andSingle-exitA cat-back exhaust system that replaces it with the above.A grade that shapes its sound through structure alone, without a valve. In the TODOROKI™ M240i G42 line,The Most Accessible Priceis set to the above.

This productMade to orderThis is made to order. Once your order is confirmed, we build one unit exactly to your chosen specification.

The TODOROKI™ SINGLE has no valved exhaust. This is not a stripped-down specification, butA grade built on a different design philosophy.

A valved exhaust is a mechanism for switching volume, but the trade-off isMoving parts and electronics are placed partway along the exhaust path. The valve itself, the actuator, the wiring, the controller — all of these sit in a place that's constantly exposed to heat and vibration.

In a configuration without a valve, none of these exist in the first place.Nothing to fail, and no wiring work required. Installation is completed simply by reconfiguring the exhaust system. AndThat difference is reflected in the price. The price difference from the valved TODOROKI™ VALVE RS is ¥100,000.

In return,There's no option to drive quietly. The volume is the same at cold start as it is through a residential street. If you want to change it to suit the situation, choose TODOROKI™ VALVE RS.

The factory M240i G42 has dual exits, one per side. The TODOROKI™ SINGLE takes this andA configuration that consolidates into a single exit.

Changing the number of tips is not simply a design change.the length of the exhaust path, the weight at the rear of the car, and the directionality of the sound all changeWhile a split left-right configuration disperses the sound, a single exit releases it from one point, so the sound is heard concentrated.

The structure itself is straightforward too. With no splitting or merging between left and right,Exhaust gases exit the car via the shortest possible route. Because the B58 is a single-turbo and exhaust exits the turbo already combined into one stream,This pairs well with a configuration that carries it straight through as a single pipe, you could say.

This is a configuration people feel strongly about either way. If you want to keep the factory left-and-right exit layout, consider TODOROKI™ VALVE RS.

This product's packaged weight is16.0kgThat's the figure. Since the exhaust's weight sits at the very rear of the car,Even at the same weight, it has a greater effect on handling than mass placed at the centre of the caris the part.

The reason for the light weight lies in the structure: the branch to left and right, the second silencer, the valve mechanism and actuator.A single-exit, valveless configuration has none of these. Part count shows up directly as weight.

• An exhaust path with no moving parts: Since there is no valve, nothing obstructs the exhaust path. The exhaust follows the same path across the entire rev range
• Single-exit: Consolidates the exit into a single pipe. Compared with the factory's dual-side exit, the rear-end look changes fundamentally, and the sound is concentrated into one point
• Cat-back Structure: The factory catalytic converter is left in place, replacing only the section downstream of it. As it uses the factory hanger positions, no modification to the vehicle is required
• Compatibility with the B58: with a single turbo, the gas leaves the turbine already gathered into one path. Routing it without splitting left and right keeps resistance through the system to a minimum

This productBuilt to match the mounting hole positions of the factory parts. As the factory hanger positions are used as-is, it installs without any modification or welding to the car.

The base material is SUS304 stainless steel, 1.5mm wall thickness. The surface isSandblasted finishgiving a subdued texture unlike a mirror finish. Because it doesn't reflect light strongly, it doesn't stand out too much once fitted underneath the car.

Manufacturing is handled by a specialist factory that holds production tooling for the major models.13 Years Specialising in Exhaustis a factory with a proven track record in the above.

Three grades are available for the M240i G42 (B58).With or without a valved exhaustandMaterialplease choose accordingly.

The ¥100,000 difference between this product and VALVE RS isThe valved exhaust mechanism and the breadth of optionsThis is the case. For those who don't need to switch volume and simply want the single-exit look, this product is the most rational choice.

SINGLE is the grade that builds its sound through construction alone. There is no valve — no moving part at all — and what that saves goes into material, construction and the price.The silencer body features the TODOROKI™ logo. As a brand, we apply this to every product regardless of price point.

Focusing exclusively on BMW lets us share jigs and validation processes across products, and reading demand chassis by chassis removes the losses that come with small-batch production. Optimising every stage — administration, manufacturing and shipping — is what makes this price possible.

TODOROKI™ is made to order, one car's worth at a time, in partnership with our production facility. Fabrication begins once your order is confirmed, and BIMMER+ selects and inspects every specification before dispatch.

• Customization available on request: We're happy to discuss exhaust specifications with you before purchase
• Volume direction can also be specified: It lets us accommodate requests like "I want it louder" or "I'd like it a bit quieter"
• Additional Charges: Additional charges may apply depending on the specification
• Prior consultation required: If you'd like customisation, please be sure to contact us before purchase
• Notes: Some customisations may not be available depending on production status or vehicle model

We are publishing actual exhaust-note recordings progressively as they become available for each model. If you're in a hurry, please use the contact form to"Vehicle model and chassis" and "sound sample request"Please include this when you contact us. For models we already have a sound sample for, we'll send it as is; for models still in preparation,We prioritise preparation for vehicle models based on customer requests.

BMW M240i G42 (B58)Purpose-built design. Also fits the M240i xDrive.

BIMMER+ organises its collections by chassis code. Search from your own chassis and only the parts that fit will appear. Model year, trim and prior modifications may mean some adjustment is needed at fitting, so please ask before you buy if anything is unclear.

The listed priceShipping, customs duties, and customs clearance fees are all included.There are no additional costs after the product arrives.

Exhausts are bulky and heavy, and shipping alone runs to around ¥20,000. Some sellers bill freight and domestic forwarding separately from the product price; BIMMER+ quotes one all-inclusive figure.

After your purchase, be sure to"Vehicle model / year / VIN" via our contact form. Even if you do not want any customisation, please still get in touch so we can identify your car.

Removing and installing the exhaust requires specialised tools and a lift. We strongly recommend installation by a workshop or pro shop with the relevant expertise.

This product has no valve, so no wiring work is needed. On cars with a factory valve, however, removing it may trigger a warning light, in which case a canceller or similar solution will be required.

As these are built to order, shipping after order confirmation typically takes2–4 weeks. Customisation, production and logistics can push this beyond the stated period. If you are working to a deadline, talk to us before ordering.
