RoadsterSport Midpipe with Catalytic Converter and Resonator :: 99-05

The factory converter for the 1999 to 2005 Miata is a welded in part of the midpipe (California 99-00 Miatas also have second converter in the header assembly). This is the best BOLT IN midpipe available for second generation Miatas and includes a highflow converter and built in resonator! Full 2.5 inches from tip to tip in all stainless steel. ALL the mufflers we sell for 99-05 include only the muffler and not a midpipe (unlike the 90-97 choices). So if you want the flow to connect your new high flow header to your new high flow muffler here it is...for normally aspirated to supercharger or turbo (BUT does NOT fit MAZDASPEED). All stainless steel parts means years of quality performance. Not CARB approved. Has factory location O2 connection...and optional use extra connection in the cat for EGT. YES, fits anywhere your factory 99-05 midpipe fits! Not for use with Racing Beat's lower rear chassis brace.
