I just received and email back from www.getBMWparts.com (Tischer BMW in Maryland) stating there’s no performance enhancement on the exhaust other than the looks and sound for the system. I'd be ashamed to even release an exhaust for it being strictly cosmetics and to even classify it as an "M Performance product" Come ‘on BMW, stop being stingy and manufacture some "high performance" mods.
