It looks like the MWC Kmember group purchase is gaining traction. If you are interested please send an email to: [email protected]
with "4th gen kmember goup purchase" in the subject line. Also let them know what configuration you are looking for.
Their kmember supports 5" downpipe on the passenger side and a 3.5" downpipe on the driver side. More information can be found here. http://midwestchassis.mysimplestore....ebird-trans-am
