The Slip-On Line (Titanium) comes with a specially developed Akrapovic control kit for a complete sound experience. The sound character offers a rich tone at normal cruising, rising to a deep sporty sound when the M3\/M4 is driven more dynamically. It serves up a perfect sound at all rpms, delivering comfort and sportiness in one exhaust. A ground-breaking octagonal shape has been fashioned from lightweight titanium with a carbon-fibre outer sleeve for the tailpipes, and for more traditional buyers there is the classic cylindrical design.The system delivers power increases of 8.0 kW (10.9 hp) at 6,000 rpm and a torque gain of 13.9 Nm at 5,000 rpm when tested on The Akrapovic dyno against a BMW M4 Competition with a standard stock exhaust. Remapping is not needed for this configuration, and it fits all vehicles (OPF and non-OPF), but the ECE certificate is valid only for cars equipped with an OPF filter.Optional link pipes and downpipes are available for customers looking to change the exhaust for closed circuit usage. An optional Akrapovic Sound Kit is also available. With the installation of the optional link pipes, downpipes, and Akrapovic Sound Kit, ECE type approval of the Slip-On Line (Titanium) is no longer valid. An optional hand-crafted carbon-fibre rear diffuser is also available to add an extra visual impact to The Akrapovic tailpipes.The exhaust system also fits on xDrive, CSL, LCI, M3 Touring (G81), M4 (G83) Competition and Convertible models. The ECE type-approval certificate is not valid for CSL model.The Slip-On Line (Titanium) exhaust system is ECE type approved for cars equipped with an Otto\/gasoline particulate filter.The Tail Pipe Set (Carbon) has to be ordered separately as a mandatory part.

In place of the forward factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes which are commonplace in the market. This hand-made 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is present in the stock system. Along with the inherent benefit of increased volume by removal of the resonators, the Dinan X-Pipe for the G8x M3\/M4 produces a louder, smoother, and fuller exhaust note that will deliver smiles time and time again.\u003c\/p\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDeletes resonators between the secondary catalysts and rear muffler for increased volume\u003c\/li\u003e\n\u003cli\u003e5-pounds lighter than the stock mid-section (Stock: 22-pounds vs. Dinan: 17-pounds)\u003c\/li\u003e\n\u003cli\u003eIncludes X-pipe crossover made from mandrel bent tubing for minimum restriction\u003c\/li\u003e\n\u003cli\u003e76mm (3-inch) tubing replaces stock 70mm (2.75-inch) tubing for free flow\u003c\/li\u003e\n\u003cli\u003eFactory-like fitment with included mounting hardware\u003c\/li\u003e\n\u003cli\u003e100% 304 stainless steel construction\u003c\/li\u003e\n\u003cli\u003eSmoother, louder and sportier sound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot legal for sale or use on pollution-controlled vehicles in California.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":67746843820184,"sku":"DNND660-0094","price":899.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/8567\/1064\/files\/c05ef41c21f31d3b87ef9ff7c19836aeL_9e782f08-218e-4416-b695-f91872cfb027.jpg?v=1792285338"},{"product_id":"mbrp-2021-bmw-m3-m4-3in-axle-back-dual-rear-exit-w-t304-ss-carbon-fiber-tips","title":"MBRP 2021+ BMW M3\/M4 3in Axle Back Dual Rear Exit w\/ T304 SS Carbon Fiber Tips","description":"\u003cp\u003eTHE ONLY EXHAUST YOU\"LL EVER NEED - MBRP Armor Pro Series exhaust systems are backed by a Lifetime Warranty and crafted out of T304 Stainless Steel - the most durable material grade that money can buy.\u003c\/p\u003e\n\u003cp\u003eThe T304 Stainless Steel tubing is easy to clean and maintain.
