Hey guys I'm looking to put some mods in my car and I'm not sure which to do. There's some that I know I want but I want to know what some of you guys have and are running and brands, that's pretty much where I'm stuck is the brands. It's my daily so not going for race track status but I still want to get more power and torque and what else i can add or replace to make it healthier, like catch can and what not to keep the oil where it needs to be. Cosmetics as well, lights and body parts, and for anyone else that has an xi and you have a staggered tire set up what did you go with. Thanks much guys looking forward to hearing from you guys soon. Pic's welcome the more the merrier, everyone love's pic's.
I use a JB4 but the Cobb is easier to install if you cannot DIY. The JB+ is also easy to install but makes less power than the JB4 or Cobb.
There is much more you can do, but start there and add more later if you feel you need it -- downpipes, meth injection, intake, catch can.
Since the AWD and traction control use wheel speed input, look into whether disturbing the tire diameters is an issue if you go staggered. Or choose your sizes to maintain the same front to rear percentage differential as you have now. You can find specs at Tire Rack.
I figured that was good place to start. Maybe it's me but I seem to be having a hard time finding down pipes, do you/anyone else you know have and where did you guys get them? I can diy pretty well, I just don't have the space to do it yet. I'm trying to see if any friends have pit's or shops if it then I'm buying parts and taking to a shop haha. I've talked to Bmw and they said I can stagger just gotta keep the aspect the same. Just wanted to see what others have if they did decide to.
Finding downpipes for the awd models is tough. I think AR makes some. Other than that, not too sure.

VRSF, AR maybe others for 535i. Don't know about 535xi.. Google.
The VRSF pipes for the rwd will fill but the front pipe has to be modified to clear the front diff.
So I'm thinking about doing AR down pipes and JB4 with Bluetooth soon and I wanna do an exhaust to, but I don't want a cheap sound. I like the deep and quiet till you get on it sound. When I the AR's I'm gunna do catted, should I get resonators with it or with it and do I need an exhaust and if so sounds like everyone does axle back, what's your guys take on it?
AR downpipes, FMIC (7 inch VRSF) and MHD stage II tune (unless you want logs then go with the JB4).
I recommend going without cats or resonators on the downpipes. As far as exhaust best bet is muffler delete. Follow threads by ucsbwsr, he's the leader of the pack for E61 modifications.
