FMF Powerbomb Stainless Steel Motocross ManifoldHONDA 250 CRF 250 R (ME10) - 2006 - 2009Ref : 1822-0089 / 18220089

The PowerBomb collector uses a patented module from FMF that precisely locates the exhausts during the first stage of the pipe. The position of the PowerBomb collector increases performance by 10%.
It acts as a pre-silencer, helping to reduce noise levels.
Expansion and contraction of exhaust sounds via the collector allows for a higher flow rate.
It is available in some cases in stainless steel to optimise strength while maintaining lightness, or in titanium to minimise weight.
