TODOROKI™ VALVE RS Made-to-Order X-Pipe Valved Exhaust｜BMW M3 E90 / E92 / E93 (S65)

The S65 is a 4.0-litre naturally aspirated V8.The E9x M3 was the last naturally aspirated M engine to rev to 8,300rpm. Now that forced induction is the norm, no M3 will ever rev out like this again. The factory exhaust, though, is designed to deliberately suppress sound pressure through its silencers.You're not experiencing the V8's revs through sound. This is the source of the first thing that feels lacking on the E90 / E92 / E93 M3.

TODOROKI™ VALVE RS X-pipe replaces everything downstream of the catalytic converterQuad-exit cat-back system.An X-pipe that cross-connects the left and right bankspairs this with an electronically controlled valve.Factory-equivalent quiet with the valve closed, and the S65's true high-rev sound when openrestoring it.

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

The S65V8. Each bank handles four cylinders and the exhaust runs independently down each side. Nothing converges into a single path the way it does on a straight-six.Where — and how many times — to join the two independent systems. V8 exhaust design comes down to this point.

The principle behind cross-connection is this. The instant one side exhausts, that flow creates a depression inside the pipe. Join the two sides and the depression pulls gas out of the other bank. That is scavenging.

The X-pipe takes the left and right paths andCross-connects at a single point. This structure crosses the V8's two independent exhaust systems to bring the scavenging effect into play.

Unlike simply enlarging the pipe diameter to gain flow,you can extend high-rpm flow without losing low- and mid-range torqueis the essence of a crossed structure. With the left and right exhaust merging once, the low end also gains more depth.

For those seeking a more aggressive configuration, we increase the cross-connection points to two, TODOROKI™ VALVE RS Dual Z-pipe . We offer this.

If pure exhaust efficiency is your only goal, this is the most rational configuration.however, since the mid-pipe has no sound-damping element, the volume stays constant at all timesis a weakness here — whether driving through a residential neighbourhood or starting the engine early in the morning, the volume never changes.

The valved exhaust is what solves this.

• Valve closed: A quiet path that runs through the centre exhaust. Volume drops to near-factory levels, so it won't be an issue when driving in residential areas or starting the car early in the morning
• Valve open: The straight path opens up, maximising exhaust efficiency

Exhaust efficiency and quietness are normally a trade-off, but a design that switches the flow path itself lets you have both.Release exhaust — shaped by the X-pipe — only when needed. Because the mid-pipe has no silencing structure by design, the difference between valve open and closed is larger.

• X-pipe: cross-connects the two banks. The depression created as one side exhausts is put to work by the other, producing a scavenging effect. Flow improves without the usual loss of mid-range torque, and the note gains body at the bottom end
• Centre exhaust: A single silencer is positioned at the centre of the car. With the valve closed, exhaust routes through it for sound suppression; when open, it's bypassed
• Electronically controlled valve: switches the exhaust path just before the silencer. Closed, gas runs the quiet route through the silencer; open, it takes the straight path — so volume and character change together
• Quad-exit: Exhaust exits through four tips, two on each side. This configuration secures exhaust efficiency while achieving an appearance befitting an M model
• 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. TODOROKI™'s unit for the E90 / E92 / E93 M3,Designed from 3D scan data of an actual car's underbody. Factory hanger positions, floor geometry and clearance to the rear bumper aperture are all pinned down from measured values, so it fits without modifying the car.

Welding isFully TIG-welded at high temperature. The base material is SUS304 stainless steel, with a wall thickness of 1.5 mm. The surface isPolished finish. Since the exhaust system is constantly subjected to both heat and vibration, the quality of the joints directly determines durability.

The S65 is naturally aspirated.Without a turbo acting as a damping element in between, the sound of the combustion chamber travels almost directly into the exhaust pipe. On a turbocharged car, part of the exhaust energy goes into spinning the turbine and the note rounds off with it. A naturally aspirated engine has none of that. Change the exhaust and the change arrives, undiluted, as sound.

What's more, unlike a straight-six, a V8 has no structure that naturally cancels out primary vibration. The exhaust from the left and right banksHow they're connected determines the very quality of the soundThis is exactly where a crossed structure pays off. It draws out the S65's high-rpm range — which revs to 8,300rpm — in terms of sound.

The difference is the number of cross-connection points and the material. The X-pipe on this product delivers scavenging perfectly well. If you want to push further, look at the dual Z-pipe; if you also want the weight saving and the heat-coloured finish, look at the full-titanium TITANIUM.

RS is a grade designed around one standard: no compromise on price, quality, or sound.The silencer body features the TODOROKI™ logo. If we are going to put our name on it, it goes on every product regardless of price point. Costs that contribute nothing to performance or sound are not carried; that money goes into material, construction and the price.

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.

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 E90 / E92 / E93 (S65, 4.0L V8)Purpose-built design. Fits the sedan (E90), coupe (E92), and convertible (E93) alike.

It does not fit non-M3 E9x models, such as the straight-six 335i, so please take note.

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 fitting an exhaust requires specialist tools and a lift. We strongly recommend installation by a qualified workshop or specialist. Wiring for the valve controller is also involved, so if you are not confident about fitting it yourself, please use a professional.

On cars with a factory valve, removing it may trigger a warning light. If that happens, 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.
