Exhaust GIANNELLI Racing for motorcycle KTM RC 125 and 390 4T before 2017

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!

View of the X-PRO version, very short and typical competition!

Several choices are available to you :

-The GX ONE color nichrom

-The X-PRO color nichrom BLACK

-The IPERSPORT color aluminum, black or titanium with carbon tips

View of the IPERSPORT aluminum color version:

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!

This is a very clear beautiful exhaust line, rare, with several choices, powerful, it is also delivered with a DB KILLER to muffle the noise, can be removed and delivered to infinity according to your desires and needs.
