In the field of aftermarket tuning, Hoermann is proud to announce a details of their extensive tuning package for the Alfa-Romeo 156 3.2 V6 24V GTA.

To give the GTA the correct sound, Hoermann offers a stainless steel exhaust system. The two oval exhaust pipes (148 x 75 mm), award the 156 GTA a distinctive note that is easily remembered and recognized.
