be careful!!!

dOING IT FOR A SHORT PERIOD OF TIME MIGHT BE OKAY BUT LONGER THAN A WEEK OR FREEWAY DRIVING WILL CAUSE DAMAGE TO YOUR CATALYTIC CONVERTORS. BMW ADDED THIS DUE TO THE NOISE REDUCTION BUT ALSO THE DUAL PIPES ON THE 335 TAKE TURNS RELEASING EXHAUST FUMES. tHE AIR FUEL MIXTURE MIGHT GO LEAN OR RICH AND CAUSE YOUR CATS TO BURN. TRUST ME I KNOW
