Hi, I’m looking for a FMF high mount header for the 14-15 grom. Or a header that will fit the fmf 4.1 RCT slip on exhaust. The fmf slip on outside diameter (OD) 34.5mm and inside diameter is 31.6mm. The 14-15 chimera stainless header fm steady garage didn’t work. The outside diameter is too narrow even with the factory slip on gasket clamped down. Thanks.
