Have you tried the CSC test?

Don’t forget the rear end! If you are unlucky enough to have to drive a slow vehicle on a motorway take a look at 156s as they stream past---the majority are spoiled by the cheap looking uninteresting exhaust tail pipe. Occasionally a car with a CSC tail pipe passes and what a difference! The CSC tail silencer, finished in matt black, boasts a superb stainless steel tail pipe giving every 156 character, individuality and a pleasant exhaust note befitting to the Alfa Romeo badge on the grille. When your 156 requires a new exhaust tail box----remember the “CSC Test”.
