FULL FI EXHAUST for my BMW M340i is INSANE by AutoTopNL
The 200Cell downpipe for the M340i is the ultimate entry-level mod. Because you don't get any warning lights. It's just plug-n-play. And it offers more sound and a bit more power even. It's fantastic. And now we've gone further with a complete exhaust setup, which offers a perfect fitment and eliminates any droning and rattling you'd from another aftermarket exhaust. - AutoTopNL
