TODOROKI™ SINGLE Made-to-Order Straight Single-Exit Exhaust｜BMW M3 G80/G81 / M4 G82/G83 (S58)

The S58 is a 3.0-litre twin-turbo straight-six — the current M engine, fitted to the M3 G80/G81 and M4 G82/G83. A closed-deck block and forged crank make it a substantially different animal from the S55. The factory exhaust, though, has to carry both emissions compliance, OPF included, and noise regulation.Only the exhaust note is being suppressed relative to the engine's true character. This is the source of the first disappointment most owners notice on the G8X.

TODOROKI™ SINGLE takes everything from the catalytic converter back andSingle-exitA cat-back system that replaces it with this. The mid-pipe isStraight-through constructioncarries the exhaust to the silencer by the shortest route.A grade that shapes its sound through structure alone, without a valve.

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. It's the most accessible price point in the TODOROKI™ line for the G8X.

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 S or above.

This product's mid-pipe isStraight-through constructionis such a path. It has no resonator and no bends, sending exhaust straight from the catalytic converter to the silencer.

In a configuration that narrows the exit to a single pipe, every branch and merge point directly adds resistance.Instead of splitting left and right, it runs the shortest distance through a single pathA single exit is structurally advantageous in this respect. Since it also has no moving parts such as a valve,Nothing in the path obstructs the exhaust.

The factory M3 G80 / M4 G82 has 4 tips split left and right. This product consolidates that into one.the length of the exhaust path, the weight at the rear of the car, and the directionality of the sound all change. Where four tips spread the sound left and right, a single exit releases it from one point, so it sounds more concentrated.

This is a configuration people feel strongly about either way. If you want to keep the factory quad-exit look, consider TODOROKI™ VALVE S or above.

• Straight Mid-pipe: no resonators, no bends, no resistance. Gas velocity is carried through to the silencer intact, so the system is far less likely to choke high in the rev range
• 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
• Silencer Internal Structure: packed with heat-resistant stainless wool and sound-absorbing fibre. Compared with ordinary glass wool it degrades far less under heat, so silencing performance holds up over the long term
• Single-exit: Consolidates the outlets into a single exit. This fundamentally changes the rear-end impression compared with the factory quad-exit layout
• 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

Exhaust fitment precision is determined by the actual car, not by drawings. This productDesigned based on the actual car's chassisand clearance against the factory hanger positions, floor shape, and rear bumper opening is verified with actual measurements.Because a single-exit layout differs greatly from the factory routing, this measurement accuracy directly determines whether it fits. Designed to install without welding or modification to the car.

The flangeTIG-welded After CNC Machining. Flange face accuracy is what stands between a sealed system and a leaking one, and how precisely it is machined is how well it seats. The base material is SUS304 stainless steel at 1.5mm wall thickness, with a brushed surface finish.Every unit is inspected before shipping.

6 grades are available for the M3 G80/G81 and M4 G82/G83 (S58).With or without a valved exhaustandNumber of Tips, andMaterialplease choose accordingly.

⚠️ This item and the SINGLE TITANIUM do not fit the M2 G87. REAR, VALVE S, VALVE RS and VALVE RS TITANIUM also fit the G87. Single-exit systems are listed separately because the rear-end structure differs from car to car.

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 M3 G80/G81 / M4 G82/G83 (S58)Purpose-built design.

⚠️ Not compatible with the M2 G87.Single-exit systems differ because the rear-end structure varies from car to car. For the M2 G87, consider TODOROKI™ REAR, VALVE S or VALVE RS.

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.
