We didn’t like this design, so we changed it — there is no longer a squish, the whole system remains a fluid 4”, and it comes with an extended brace.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHear it in action:\u003c\/strong\u003e \u003ca href=\"https:\/\/youtu.be\/YPiZlfci-YY?si=OG0PI_5lh-yAim7D\"\u003eChris Borges' video featuring this system — fly-by and rev clips\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003e\u003cspan\u003e\u003cbr\u003eFrom initial sketches to detailed 3D models and our final prototype, RVNG is proud to announce the release of the first-ever 4” Full True Single Midpipe Quad Tip Valved Exhaust System for the F8X S55 platform—a groundbreaking system designed to redefine sound, flow, and performance.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eThis isn’t just a bigger pipe—it’s a completely reimagined exhaust solution. Our 4” true single midpipe eliminates the restrictive factory dual-pipe and 3.5” crossover designs seen in other systems, allowing for smoother, uninterrupted flow from the downpipes all the way to the rear muffler section. The result? A deeper, more refined exhaust tone with less rasp, reduced backpressure, and optimal turbo efficiency—especially at higher RPMs.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eThe system also features an OEM-style electronic valve control, giving you the ability to switch from a quiet, neighborhood-friendly tone to a raw, aggressive sound at the press of a button.
