BMW X5 4.4i X-pipe Installation Video and Soundclips. 

The sound is actually not that loud on the highway. The only noticeable difference from the stock exhaust is during initial start up. That's when it sounds a bit louder, like an M3 coming to life, especially in the early morning then eventually tones down as the engine gets warmer..

I'm not really sure how the Magnaflow looks like but the box it came in said Monster Flow.. My brother bought it for me for around $60.00.

It's sound pretty good can you please tell me where i can get it. i am in the US Thanks

Did your check engine light come on? Do X5's have post cats?

Sounds ok, I bet the drone is really annoying on the hwy though.

Filipino rap music?The Exhaust Sounds good though nonetheless.

Hey I'm sorry but I don't really know where my brother got the x-pipe but I'm sure you can search for it online by typing Flow Monster x-pipe or you can search xoutpost.com for various brands other X5 owners are using.. Hope this helps.

You ruined the nice V8 sound an X5 has.
