Expansion exhaust BUD HGS KTM SX 105 2018-2022

Exhaust expansion developed by Bud-racing and built by Hgs.

Hgs is one of the exhaust system suppliers of the largest European teams.

This expansion promises greater recovery at low revs (eliminating engine gaps) and power gain over the entire engine rev / rpm range.

Each muffler is developed based on the weaknesses of each bike in order to fill the gaps in the standard exhaust.
