Stealth Cat-Back Exhaust: Mk7 / Mk7.5 GTI (2015-2021, MQB) | 3" Dual-Exit, Triple-Silenced

The Stealth Cat-Back is our quietest full-system build for the MQB Mk7 and Mk7.5 GTI: a hand-built 3" dual-exit cat-back engineered for the OEM+ crowd who want a deeper, cleaner note with the drone completely dialed out. Three separate stages of sound control across the system make this the sleeper setup: aggressive when you're in it, dead quiet at a highway cruise. Fully TIG-welded, argon back-purged 304 stainless, built to order. Triple-silenced: the stealth sound package Mid-pipe section, Vibrant 17950 resonator. A 3" resonator up front smooths the note right off the downpipe. Front muffler section, Stainless Bros 3" thin oval muffler. Mounted ahead of the rear diff, it knocks down the mid-range without choking flow. Rear axle-back section, Vibrant 10635 StreetPower transverse oval muffler. A single 3.5" inlet splits into a true dual 3" exit, so the rear stays clean and drone-free. Want it louder? The Aggressive cat-back runs the same front end with no rear muffler.
