BMW X5 M60i German Car Accessories/GCA Valved Sport Exhaust

Absolutely LOVE my new exhaust from German Car Accessories! This thing sounds NASTY. The cold starts are my favorite. I drive with the valves open 99% of the time as there is ZERO drone at highway speeds. But if you want that ultra quiet experience, just close the valves with the included remote. I cannot recommend these guys enough!

Is it titanium or stainless? Also did you get any CEL?
