More affordable than the ARROW line, and yet of the same quality!

Although the silencers are often less aesthetically appreciated than the ARROW, these GIANNELLI lines remain excellent sports lines!

The line comes complete with the first stainless steel tube, the silencer, all the mounting hardware, and the catalyst if you select the catalyzed option!

This option is ideal for countries where a technical control is in place and where pollution must be tested! The sport catalysts are more efficient than the origin, and remain approved for the road therefore in the standards of pollution.

The versions without catalyst are obviously more powerful and offer a better noise, moreover, in case of reprogramming, we can aim for a poorer AFR (in the 13) without risk for the catalyst since it is no longer there!
