MagnaFlow Street Series 貓背式性能排氣系統 15310

The deep, aggressive tone at startup is exactly what my Q50 needed to feel more alive. Install took about an hour with basic tools, and there's zero drone on the highway.

Finally got this on my Q50 and the cold start rumble is exactly what I was hoping for — deep but not obnoxious. The 5-inch double-walled tips look aggressive without sticking out too far.

Installed it over the weekend and the resonant tone at cold start is addictive, but it's the highway drone-free cruise that sold me. Fitment on my Q50 was spot-on, no modifications needed.
