BMW 420D M SPORT TOURING

BMW 420d M Sport – Downpipe-Back System & Dual Exit Conversion at MIJ Exhaust! 🔥

This BMW 420d M Sport paid us a visit at MIJ Exhaust for a full downpipe-back exhaust system, finished off with a dual exit conversion — a serious upgrade that transforms both sound and presence. 😎

Designed to improve exhaust flow and sharpen the driving experience, this setup delivers a deeper, sportier tone without losing the refinement you want from a daily-driven diesel. The downpipe-back system frees up performance, while the dual exit conversion gives the rear end a much more aggressive, M Sport-worthy look.

The result?
💨 Better flow
🔊 Better sound
👀 Better stance

A perfect balance of performance, style, and everyday usability — exactly how the 420d M Sport should feel.
