Introducing the second generation RoadsterSport ND Midpipe; the only full 5" diameter body ultra highflow 200 CPI Spun Metallic Converter ND Midpipe on the market. Combined with 2.5" stainless piping, a Magnaflow high density non-fiberglass resonator that will not burn out, and made to last in all stainless steel, this is simply the best high performance ND Midpipe available. Not CARB approved and cannot ship to an address in the state of California or Colorado.


Designed as a bolt-on replacement for the factory midpipe to carry higher flow from the larger pipe size all the way out any RoadsterSport brand muffler.

All Mandrel bent tube with no tight bends to slow flow, notice how smooth and flowing the bends are!

 Instead of the OEM ball/socket outlet, this midpipe converts to a flat flange to carry more flow all the way out through any of the ND RoadsterSport mufflers, that means this midpipe only works with RoadsterSport brand mufflers. A stainless flex joint replaces the function of the ball/socket connection to allow for greater flow.

This midpipe incorporates the largest and highest density packing stainless resonator that can fit neatly under the Miata, so even with greater diameter and flow, the sound is mellow and fun. This part will still raise your cars final sound level because of the much higher flow.

 Includes O2 sensor bung after converter which means you are ready to add a performance header.
