Mazda gave us a serious challenge with the ND model MX5 mid-pipe design but we got it figured out.
All the Goodwin RoadsterSport mufflers fit BOTH the 1.5 and 2 litre, either manual or auto transmission. The mid-pipe also fits the 1.5 manual transmission and the 2 litre in either auto or manual.
Instead of the small ball/socket outlet of the stock mid-pipe we convert to a flat flange so we can carry more flow all the way out through any of our RoadsterSport mufflers. That means this MX5 mid-pipe ONLY works with our RoadsterSport brand mufflers. To replace the function of the ball/socket connection but allow for greater flow we use a stainless flex joint. The stainless flex joint adds significant costs but was the best way to max flow and performance all the way out. Likewise we stuff the largest and highest density packing all stainless resonator that can fit on the car so that even with greater diameter and flow the sound is mellow and fun, not harsh and abrasive.
All Mandrel bent tube with no tight bends to slow flow, see the picture and notice how smooth and flowing the bends are!
Designed as a bolt-on replacement for the factory mid-pipe to carry higher flow from larger pipe size all the way out any of our RoadsterSport mufflers. Simple Bolt on!
INCLUDES TWO O2 SENSOR CONNECTIONS which gives YOU the option to later add our RoadsterSport headers and avoid engine codes (by relocating the factory O2 sensors to before and after the converter in this mid-pipe from their stock location before and after the converter that is in the factory header when you replace that header).
All stainless steel construction for years of driving pleasure. This MX5 mid-pipe is larger 2.5 inch diameter pipe size. Uses high quality SPUN catalytic converter with metal core. Uses monster size because when you uncork this ND MX5 motor it wants to get loud unless you use a resonator this large (by comparison stock resonator is much smaller).
Despite very large resonator, this mid-pipe will raise the final sound level just slightly because of the higher flow larger diameter tubing.
BRIAN'S APPLICATION NOTES: I love the sound of this mid-pipe in combination with our RoadsterSport Helmholtz mufflers, adds burble and throatiness when you push toward redline and controls the off throttle resonance these motors will otherwise make. We could have done a cheaper mid-pipe, but we decided to do the best for those of you who demand the best.
FREIGHT & SHIPPING NOTE: Due to the size of the mid-pipe box delivery can only be made to non residential addresses. Please email email@example.com after placing your order and we'll work with you to find the best delivery solution.
