Like all Dinan exhausts, our 328i\/428i Free Flow Exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. \u003cbr\u003e\u003cbr\u003eThe system is built with ease in mind and utilizes a simple bolt-on installation with included mounting hardware. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 70 mm ceramic black or polished and laser engraved exhaust tips for a tasteful, high-performance look that yields a maximum performance gain of 4 horsepower and 3 ft-lbs of torque.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e \u003cbr\u003eFeatures: \u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"background-color: initial; letter-spacing: 0px;\"\u003e+4 HP @ 6600 RPM, +3 lb\/ft @ 6600 RPM\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"background-color: initial; letter-spacing: 0px;\"\u003eUses the factory brackets and hangers for a factory-like fitment\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"background-color: initial; letter-spacing: 0px;\"\u003eWeight Savings\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"background-color: initial; letter-spacing: 0px;\"\u003eDinan's Tuned Resonance Chamber Technology\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003e100% 304 stainless steel construction\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003e\u003cspan style=\"letter-spacing: 0px;\"\u003eTwin 70mm (2.75\") laser engraved polished stainless steel or black ceramic exhaust tips\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cb\u003eInstallation Instructions: \u003c\/b\u003e\u003ca href=\"http:\/\/files.dinancars.com\/webresources\/datasheets\/18fff2434fab5701f069421114e73e2e.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDinan F3X 328i\/428i Axle-Back Exhaust D660-0046 Instructions\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/a\u003e \u003cbr\u003e \u003cimg src=\"http:\/\/files.dinancars.com\/webresources\/images\/products\/D660-0046_1.jpg\" style=\"max-width: 100%; height: auto;\"\u003e\u003cbr\u003e\u003cbr style=\"line-height: normal;\"\u003e\n\u003cp\u003e\u003cb style=\"font-size: 12px; background-color: initial;\"\u003eVEHICLE FITMENT\u003c\/b\u003e\u003c\/p\u003e\n\u003cul style=\"letter-spacing: normal;\"\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12px;\"\u003eF30 \/ F31 \/ F32 \/ F33 BMW 328i \/ 428i - N20\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dinan","offers":[{"title":"Black Ceramic","offer_id":52652240175384,"sku":"D660-0046-BLK","price":245520.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/4514\/4856\/files\/x661yrdea0z4_e8dd5bfa-b7cf-4b9a-a3e1-81ef950d9b8e.jpg?v=1789073531","url":"https:\/\/driveforges.com\/products\/dinan-free-flow-axle-back-exhaust-for-bmw-f3x-328i-428i-5vlsz5","provider":"Drive Forge","version":"1.0","type":"link"}
