If the Z-pipe is the structure that connects left to right, equal-length is the design that aligns when each side's gas reaches the junction. Unequal path lengths put the exhaust pulses out of phase, and scavenging will not work as intended however you cross them. Equally, matching the lengths alone achieves nothing if the two sides are never joined — there is nothing there to draw against.\u003cspan class=\"bm-emph\"\u003eEqual-length and the Z-pipe are a combination that isn't complete with just one or the other\u003c\/span\u003eis the case. TODOROKI™ builds all 6 mid-pipe types with an equal-length design.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eHowever, this structure does have a weakness.\u003cspan class=\"bm-emph\"\u003eThe better the flow, the more quietness is lost\u003c\/span\u003e.

Overview\u003c\/div\u003e\n\u003cp class=\"bm-text\"\u003eThe S58 is a 3.0-litre twin-turbo straight-six, generating thick torque from low revs. The factory exhaust, though, deliberately suppresses sound pressure with an OPF and silencers. Accelerate and nothing follows. That first sense of something missing in a G80, G81, G82, G83 or G87 comes from the exhaust, not the engine.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eTODOROKI™ VALVE S is a cat-back system that replaces everything after the catalytic converter. With an electronically controlled valve fitted, it is as quiet as factory when closed and lets the S58's real voice rise when open.\u003cspan class=\"bm-emph\"\u003eA grade that, by narrowing the specification, brings a valved cat-back exhaust in at ¥229,800\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eThis product\u003cspan class=\"bm-emph\"\u003eMade to order\u003c\/span\u003eThis is made to order.

From the collector after the catalytic converter through to the left and right silencers, the path lengths are matched.

Overview\u003c\/div\u003e\n\u003cp class=\"bm-text\"\u003eThe S55 is a 3.0-litre twin-turbo straight-six — the M engine that preceded the S58, fitted to the M3 F80 and M4 F82. It combines a 7,600rpm limit with a rev-out that stays clean despite forced induction. The factory exhaust, though, is designed to deliberately suppress sound pressure through its silencers.\u003cspan class=\"bm-emph\"\u003eThe engine has the character, but the exhaust note alone falls short\u003c\/span\u003e. This is the source of the first disappointment most owners notice on the F80 \/ F82.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eThe TODOROKI™ VALVE RS STRAIGHT replaces everything downstream of the catalytic converter with\u003cspan class=\"bm-emph\"\u003eSingle Exit on the Left\u003c\/span\u003e. A straight-through mid-pipe routes gas by the shortest path, and an electronically controlled valve switches the volume.\u003cspan class=\"bm-emph\"\u003eThe rear-end look changes dramatically from the factory quad-exit setup\u003c\/span\u003e.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eThis product\u003cspan class=\"bm-emph\"\u003eMade to order\u003c\/span\u003eThis is made to order.

Where four tips spread the sound left and right, a single exit releases it from one point, so it sounds more concentrated.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eThe structure itself is straightforward too.

A package that mounts a straight-six longitudinally in a body under 4.4 metres long has become a rare thing. The factory exhaust, though, is designed to deliberately suppress sound pressure through its silencers. Set against what the car itself is, only the exhaust note holds back. That first sense of something missing in an M240i comes from exactly this.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eTODOROKI™ VALVE RS replaces everything downstream of the catalytic converter\u003cspan class=\"bm-emph\"\u003eQuad-exit cat-back system\u003c\/span\u003e.

It combines a 7,600rpm limit with a rev-out that stays clean despite forced induction. The factory exhaust, though, is designed to deliberately suppress sound pressure through its silencers.\u003cspan class=\"bm-emph\"\u003eThe engine has the character, but the exhaust note alone falls short\u003c\/span\u003e. This is the source of the first disappointment most owners notice on the F80 \/ F82.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eThe TODOROKI™ SINGLE TITANIUM replaces everything downstream of the catalytic converter with\u003cspan class=\"bm-emph\"\u003eTitanium single-exit\u003c\/span\u003eA cat-back exhaust system that replaces it with the above.\u003cspan class=\"bm-emph\"\u003eA configuration without a valved exhaust, built with circuit driving in mind\u003c\/span\u003eThis is the case.

Because titanium's high strength allows thinner walls, this works as a double weight saving.\u003c\/p\u003e\n\u003cp class=\"bm-text\"\u003eThe exhaust is a component mounted at the very rear of the car.\u003cspan class=\"bm-emph\"\u003eEven at the same weight, the impact on handling is greater than if it were mounted at the centre of the car\u003c\/span\u003eis positioned there.

Titanium, compared to stainless steel,\u003cspan class=\"bm-emph\"\u003eThe top end extends further\u003c\/span\u003ethere's a tendency for the same structure to produce a different resonance.
