MagnaFlow 2006-2007 馬自達6 馬自達速度 2.3L 街頭系列 觸媒後性能排氣系統 16609

The install was straightforward on my '06 Speed6, and the sound at idle has a deep burble that's addictive. It really woke up the top-end pull without being obnoxious around town.

I didn't expect the drone-free highway cruising to be this quiet, even with the cat-back on. The deep tone kicks in just past 3,000 RPM when you want it, and the install itself was a solid afternoon project.

The deep, resonant tone on cold start is exactly what I wanted—it’s aggressive but not obnoxious. After 500 miles, I definitely feel a bit more zip in the mid-range. Install was straightforward with basic hand tools and axle stands.
