sorry, correction on the link http://www.danielsternlighting.com/home.html ... no "s"

well, just to let you know, most (if not all) after market exhausts can reduce your output by about 2HP. Stick with stock. They aren't BMW for nothing. Schnitzer and Dinan MAY make a difference, but not by much. Not worth the cash unless you like the looks.

Headers are a good upgrade, but the exhaust of BMW is a lot better than most out there. Stick with the stock BMW filter as well, it's at least 2x better than K&N's best filters..IMO anyway.

If you can't go heavy on the engine mods... that's fine... then the best advice... STICK WITH STOCK BMW COMPONENTS!!!! They're the best you can get without modifying your engine a lot. If you can, get the M5 versions of the parts you intend to replace. The only basic upgrade really worth it then is a chip.

I'd like to quote a line in BMWE34.net that I really, really love regarding aftermarket parts ... "Sorry, but you don't have a Honda." ... stick with BMW parts, they're better than most aftermarket parts. There are very few aftermarket parts that are better (although it would depend on what you want it for)

Suspension is one..if you intend to track your car, or lower it... you'll have to go with Aftermarket springs and shocks... oh, and don't buy into the "You need a lowering shock to work with lowering springs!" crap. Stick with stock or Bilstein height shocks.

Anyway, most of the best E34 info can be found on bmwe34.net there isn't anything I needed to know that I didn't find on that site! the best one out there for the e34 and it gives very practical info. Read up there, and decide for yourself

Just to let you know, I'm running 18" even though I know they slow the car down cuz they look better. I'm also running stock shocks vs. Bilsteins cuz I prefer the softer ride. And I'm still deciding on the chip or not. Chipped engines run higher octane and isn't always available here so I've put that off.

These are MY choices... the basics (and more advanced) mods are all listed in the site. Hope you find what you're looking for! Look under "Recipe for power"
