The Valvetronic Designs Valved Sport Exhaust System centers on a single 3.5\" equal-length mid-pipe that unlocks the S58's character without touching the OEM rear section, and pairs with an optional valved axle-back for even more presence and control. The equal-length design balances exhaust pulses for a smoother, higher-frequency tone, while the single 3.5\" mid-section is optimized for improved throttle response and power throughout the rev range. The system is modular by design: it pairs with the OEM or an aftermarket rear section, and the valved axle-back can be added at any time as an upgrade path.\u003c\/p\u003e\n\u003cp\u003eWith the optional valved axle-back installed, a quad-chamber muffler and OEM-style electronic valves deliver daily-driver civility with the valves closed and an aggressive, motorsport edge with them open, controlled electronically via the included controller (OEM drive-mode integration is also available). The system is compatible with OEM downpipes or free-flow front pipes and is engineered to avoid check-engine lights. It is built in T304 stainless steel or ultra-light Grade 5 titanium, with precision TIG welds, fully mandrel-bent tubing, and an included cross brace for rigidity.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTubing diameter: 3.5\" mid-pipe; 2.75\" axle-back\u003c\/li\u003e\n\u003cli\u003eMaterials: T304 stainless

profile on the G8x M3\/M4 platform. It combines a clean-sheet HFD midpipe — engineered from the ground up to optimize exhaust pulse timing and acoustic balance — with Valvetronic's signature valved axle-back system for a smoother, more exotic inline-six tone that goes beyond a simple volume increase.\u003c\/p\u003e\n\u003cp\u003eDesigned as a complete solution rather than a bolt-on afterthought, the HFD system eliminates unwanted rasp and low-RPM harshness while preserving the high-frequency character that makes the S58 come alive. With the valves closed it is refined and civil for daily driving; with them open, dual pneumatic-style electronic valves deliver a sharper, more aggressive tone under load, switchable instantly via the included controller.

performance, and an unforgettable exhaust note from the B58. The system begins with a massive 3.5\" midpipe, splitting into unrestricted dual 3\" mandrel-bent runs that flow to a set of signature Valvetronic Designs tips. With the valves open, expect maximum drama — turbospool that's impossible to ignore, aggressive overrun pops, and a motorsport-inspired tone from idle to redline. With the valves closed, volume drops by more than 25 decibels for a docile, daily-drivable setup suited to early morning starts or long highway cruises.\u003c\/p\u003e\n\u003cp\u003eConstruction is T304 stainless steel with precision TIG welds for durability and a flawless finish, also available in Grade 5 titanium for a further 21.7 lb weight savings over the factory system. Dual pneumatic-actuated valves are built for longevity and precision control, and the whole system is fully mandrel-bent for maximum flow and 100% reversible back to stock.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaterials: T304 stainless steel or Grade 5 titanium\u003c\/li\u003e\n\u003cli\u003eLayout: 3.5\" midpipe feeding dual 3\" mandrel-bent rear piping\u003c\/li\u003e\n\u003cli\u003eValves: Dual pneumatic-actuated valves for longevity and precision control\u003c\/li\u003e\n\u003cli\u003eWeight savings: 21.7 lb lighter than factory exhaust\u003c\/li\u003e\n\u003cli\u003eConstruction: Fully mandrel-bent, precision TIG welds\u003c\/li\u003e\n\u003cli\u003e100% reversible — return to stock at any time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eComplete kit as supplied by Valvetronic Designs; see the installation instructions for the full bill of materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e Valvetronic Designs ships this system as a complete bolt-on kit; no additional hardware is required for a basic installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo manufacturer install video is currently published for this specific system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eValvetronic Designs' product title references the G26 M440i Gran Coupe, but its own published Fitment tab and SKU prefix list only the G20 M340i and G22 M440i — the G26 has been left off the table below.

Valvetronic Designs answers with a full valved exhaust system engineered to unlock the Supra's hidden potential while giving the driver complete control over the sound experience. With the valves open, the system flows with minimal restriction for a raw, motorsport-inspired tone; close the valves and exhaust gases route through a quad-chambered muffler that dramatically reduces volume for daily-driving comfort — all switchable at the touch of a button.\u003c\/p\u003e\n\u003cp\u003eConstruction is T304 stainless steel for strength and durability, or Grade 5 titanium for a lighter, more exotic-sounding build. The system uses vacuum-actuated valves for instant mode switching, fully mandrel-bent tubing for unrestricted flow, and precision TIG welds throughout. Stainless steel is 11.1 lb lighter than the factory exhaust, and titanium is 25 lb lighter; 5\" tips complement the Supra's sculpted rear profile, and the system is 100% reversible back to stock at any time.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaterials: T304 stainless steel or Grade 5 titanium\u003c\/li\u003e\n\u003cli\u003eValves: Vacuum-actuated, instant open\/closed mode switching\u003c\/li\u003e\n\u003cli\u003eWeight savings vs. factory: 11.1 lb (stainless) or 25 lb (titanium)\u003c\/li\u003e\n\u003cli\u003eConstruction: Mandrel-bent tubing, precision TIG welds\u003c\/li\u003e\n\u003cli\u003eTips: 5\" tips, three finish options\u003c\/li\u003e\n\u003cli\u003e100% reversible — return to stock at any time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eComplete kit as supplied by Valvetronic Designs; see the installation instructions for the full bill of materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e Valvetronic Designs ships this system as a complete bolt-on kit; no additional hardware is required for a basic installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo manufacturer install video is currently published for this specific system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eValvetronic Designs' fitment chart lists \"2020+ Toyota Supra A90 \/ A91\" without splitting by engine displacement; this system is sized for the 3.0L turbocharged inline-six model consistent with the rest of Speed Logic's GR Supra catalog.
