Stock is too quiet and others add volume with rasp and drone. iE Catbacks bring a deep, aggressive roar under throttle, while DroneTrap™ helps keep the cabin comfortable. Give your Audi a voice. DroneTrap™ is our proprietary resonator, tuned specifically for the B9 S4 V6 to target frequencies that cause annoying cabin drone, rasp, and vibrations. Keep the roar, trap everything else.\u003c\/p\u003e\n\u003cp\u003eLook stronger, bigger, and meaner with over-sized quad slash-cut motorsport tips. No cutting or melted bumpers here, these aggressive tips fill the factory exhaust cutouts with a perfect high-end fit. No garage-door-style remote to dig out or lose. Control your iE Valved Catback just like stock from your MMI. iE PRO pr APEX Tune Suite users can take manual control with the POWERLink app on your phone or through CarPlay at anytime.\u003c\/p\u003e\n\u003cp\u003eUnlike cheap, thin-walled systems, iE Catbacks fit precisely and are built to handle heat and vibration. T304L stainless, hand TIG welds, boxed hangers, bridged piping, reinforced stamped resonators, and lap-joint connections help keep the system tight and sealed. Drive it hard.\u003c\/p\u003e\n\u003cp\u003eYou don't need a lift or a welder. The iE Valved Catback is a true bolt-on that lines up with your factory hangers and mounts, using basic hand tools. Bolt it on in your garage then let it rip.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTIG welded, mandrel bent T304L stainless steel\u003c\/li\u003e\n\u003cli\u003eB9 S4 V6T specific design iE DroneTrap™ resonator\u003c\/li\u003e\n\u003cli\u003eDual 2.5\" Piping\u003c\/li\u003e\n\u003cli\u003eFactory control \/ MMI or iE POWERlink App with any PRO or APEX Tune Suite\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated Engineering Valved Catback Exhaust System\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Integrated Engineering","offers":[{"title":"Default Title","offer_id":51885223543031,"sku":"IEEXCK13","price":1999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/0032\/1015\/files\/IntegratedEngineeringValvedCatbackExhaustSystemB9S4.png?v=1793552143","url":"https:\/\/www.gerspeed.com\/products\/integrated-engineering-valved-catback-exhaust-system-b9-s4","provider":"GERSpeed","version":"1.0","type":"link"}
