Hi As previously stated I am only selling this as I have returned my car to OEM for my project, there was never any issues with CEL's or anything of that nature. Here is the Larini weblink to the item: Ferrari 360 Modena & Spider - Larini 'Sports' Exhaust System The Larini has a great noise, the overrun is SO addictive and the noise above 4k is amazing, of course its loud as thats what we all want as it doesnt have valves (but they can be added Larini tell me). The system has done less than 1000kms and goes for over U$3500 new, I am selling it for U$2k shipped to your door. The build quality is exemplary and I've attached some pictures of the unit in my car to show you how good it looks, it really finishes off the engine bay.
