A couple of questions regarding tuning options for a 2015 X5 50i:
1. The Bimmer Performance Center recommended Active Autowerx in Miami to work with on tuning. Has anyone had experience with Active?
2. I am considering going with the downpipes - what are the pros and cons?
3. My X5 is bone stock so what other upgrades should I consider to get to a nice sleeper?
Thanks!
Cons are that your exhaust will smell like shit. Pros are that you might squeeze a couple extra ponies out of it. I'd leave the cats, but that's just me. You can leave everything stock, and still tune it and get a boat load of extra power.

1. I havent dealth with AA personally but they are a very reputable company so I wouldnt hesitate to go with them.
2. Pros- Better exhaust flow, more power (with tune). Con- your gonna get some gas smell with no cats when idling in place. Pro/Con- exhaust will be louder, especially cold start.
3. Whats your budget?
