You Won't Believe How Much Louder & Faster This M340i Got… Under Warranty!

We took a virtually brand new 2025 BMW M340i Touring (8k miles, still under warranty) and cranked it to ~420HP with a full AC Schnitzer upgrade! 😱 Watch the complete install: 👉 AC Schnitzer tuning module (plug-and-play +15% power / +20% torque boost) 👉 Full AC Schnitzer rear slip-on exhaust (stainless with carbon fibre tips, dual valves for real control) 👉 dAHler valve controller kit (remote override for open/closed modes anytime) 👉 JQ Werks magnetic shifter paddles (audible & tactile "click" feedback on shifts) Deeper, throatier sound (like a pre-GPF M340i), way more mid-range punch, and still fully warranty-friendly. This is the mod combo every M340i owner needs! If you're chasing more power without voiding warranty or spending big, hit play now. 👉 Want to watch more of our AC Schnitzer content?
