It forms the heart of Active Autowerke's full G8X system alongside a valved rear axle-back exhaust and GESI catted downpipes, suits most aftermarket exhausts and mufflers, and needs only a single cut in the stock mid-pipe. Two versions are offered: the straight-pipe gives maximum flow and the full sports-car growl, while the catted version's high-flow 100-cell flat cats drop the volume very slightly for a deeper tone.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eConstructed from 100% 304 brushed stainless steel\u003c\/li\u003e\n\u003cli\u003eX-pipe design with a scavenging effect that yields modest horsepower gains\u003c\/li\u003e\n\u003cli\u003eRemoves the two sets of factory resonators for increased flow\u003c\/li\u003e\n\u003cli\u003eFactory-style flanges and clamps; only a single cut in the stock mid-pipe is required\u003c\/li\u003e\n\u003cli\u003eInstalls to all systems that use factory-style fittings\u003c\/li\u003e\n\u003cli\u003eCatted version replaces (rather than removes) the secondary cats with high-flow 100-cell flat cats\u003c\/li\u003e\n\u003cli\u003eStock mid-pipe can be reinstated\u003c\/li\u003e\n\u003cli\u003eOne year warranty; industry-standard warranty against rust\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eComplete mid-pipe assembly with factory-style flanges and clamps as supplied by Active Autowerke; 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 Active Autowerke specifies no additional hardware for this mid-pipe — factory-style flanges and clamps are supplied.\u003c\/li\u003e\n\u003cli\u003eInstaller-supplied: an exhaust cutting tool for the single cut in the stock mid-pipe.\u003c\/li\u003e\n\u003cli\u003eOptional, to complete the full Active Autowerke G8X system: \u003ca href=\"\/products\/active-autowerke-valved-rear-axle-back-exhaust-g80-m3-g82-m4\"\u003eActive Autowerke Valved Rear Axle-Back Exhaust G80 M3 \/ G82 M4\u003c\/a\u003e and \u003ca href=\"\/products\/active-autowerke-bmw-s58-g80-m3-g82-m4-downpipe-gesi-catted\"\u003eActive Autowerke S58 G80 M3 \/ G82 M4 GESI Catted Downpipes\u003c\/a\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/active-autowerke-catalytic-converter-break-in-instructions.pdf?v=1787172533\"\u003eActive Autowerke — Catalytic Converter Break-In Instructions (PDF)\u003c\/a\u003e — required reading for the 11-087C catted version to avoid a check engine light appearing in error.\u003c\/li\u003e\n\u003cli\u003eActive Autowerke's complete installation library: \u003ca href=\"https:\/\/store.activeautowerke.com\/pages\/instructions\"\u003eActive Autowerke — Installation Instructions\u003c\/a\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart 11-087, the straight-pipe version, deletes the secondary catalytic converters.

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

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. The 3.0\" midpipe layout supports improved exhaust flow for higher-horsepower applications, including hybrid turbo setups.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTubing diameter: 3.0\" midpipe\u003c\/li\u003e\n\u003cli\u003eMaterial: T304 stainless steel\u003c\/li\u003e\n\u003cli\u003eValves: Electronic, with included controller; OEM valve-integration available\u003c\/li\u003e\n\u003cli\u003eConstruction: Precision TIG welds, mandrel-bent tubing throughout\u003c\/li\u003e\n\u003cli\u003eTips: Premium exhaust tips included on Full System configurations\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\u003eHFD midpipe assembly\u003c\/li\u003e\n\u003cli\u003eValved axle-back exhaust system (Full System configurations)\u003c\/li\u003e\n\u003cli\u003eValve controller\u003c\/li\u003e\n\u003cli\u003eExhaust tips (Full System configurations)\u003c\/li\u003e\n\u003cli\u003eHardware and clamps\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 kit; no additional hardware is required for a basic installation.
