Important Note - the images (line drawings) shown are a representation of the shape of the catalytic converter(s) for this vehicle. The end terminations (flanges and straight pipes) are illustrated accurately but the silencers and heat shielding will most likely be different from the original BMW factory part. If you want something that looks EXACTLY like the factory converter, the original BMW part (with a 1 year warranty, excluding hardware & gaskets) can be purchased through your local dealer for $1,910.00 (plus core), less any dealer discounts.
