Mazdaspeed downpipe/catalytic converter upgrade
- Product Review (submitted on September 28, 2017):
Had it two weeks now, wish I bought it earlier. Perfect fit, nice finish and instant results. I already had the full intake and this sets that off even better. Quicker spool up, smoother mid range and up top. Adds a nice rumble to the still stock exhaust. Easy to install once you get the old pipe out. Opted to install a wideband that had the o2 bung ready and at an angle to clear underneath the car perfect. I'd recommend this mod. I probably will get the exhaust next, but the sound now is even very nice.
