Mazdaspeed downpipe/catalytic converter upgrade

Product Review (submitted on September 28, 2017):
Combined with the midpipe and exhaust for MSM, this thing is part of the equation that equals the perfect solution for us stock-turbo MSM owners. Good response when the spool begins to build up. Boost feels more linear, which says a lot for these MSMs. Highly Recommended upgrade, should be a staple in a list of upgrades for an MSM.
