BBR 4-1 MX-5 NC Manifold

The must have performance upgrade for the MX-5 NC, if you only make one performance modification to your MK3 MX5 consider this as your best choice!

Used in our complete range of normally aspirated conversions our dyno developed 4 into 1 stainless steel manifold delivers the best possible exhaust flow and maximum BHP over the greatest possible rev range.

Compatible with both the standard Mazda OEM and BBR 2.5" centre section, the exclusive BBR manufactured manifold is tig welded with stainless flanges, includes 1.75" large primary tubing which surpasses all other popular (smaller primary) aftermarket options.

Please note. A change in MOT regulations May 2018 dictates that removal of a catalyst where fitted will now result in an MOT fail dependent on emissions readings. All non-catted MX-5 NC (BBR or otherwise) manifolds should be considered non MOT compliant. Please see: https://bbrgti.com/products/bbr-4-1-catted-mx-5-nc-manifold for our MOT compliant version.
