BBR 4-1 Exhaust Manifold
As seen in our Super 190 conversion!
Used as an option for our “Super 190” stage two conversion and in our complete range of normally aspirated conversions from stage three onwards.
Our in-house dyno developed 4 into 1 stainless steel manifold delivers the best possible exhaust flow and maximum BHP over the greatest possible rev range, whilst giving the 2.0 MX-5 SkyActiv the extra top end power it needs.
Countless hours of in-house testing have resulted in the best possible manifold configuration for the MX-5 ND. There is virtually no torque loss compared to 4-2-1 configurations (numerous were tested) with great higher rev range power improvements.
Compatible with both the standard Mazda OEM and BBR 2.5″ centre section. Tig welded with stainless flanges, merge collector features a pyramid for smooth transition offering the best possible flow management with reduced turbulence.
