MagnaFlow 2012-2013 Mazda 3 2.0L 加州等級 CARB 認證 直接安裝觸媒轉換器 5571146

Check engine light’s been off for three weeks straight since I swapped this in, and the mandrel-bent tubing made the whole thing feel like a genuinely solid piece. It’s CARB compliant so no headache at smog time, though I did have to wrestle the old bolts off first—that’s just the job.

The install was straightforward with the mandrel-bent tubing lining up perfectly with the existing exhaust hangers. It's been a few thousand miles now and the CARB compliance is a relief for passing smog here in California.

I was worried the check engine light would pop back on, but after three weeks of daily driving this direct-fit unit, it's stayed off without a hitch. The mandrel-bent tubing feels solid, and installation was straightforward enough for my driveway.
