AR design is what i went with. i ran mine for about 300 miles. excellent power and nice sounding turbo spool. mine are cat less. theres pretty much zero turbo lag. turbo definitely breathes a lot better. car pushed harder too! install is a PITA but its worth it. only reason im not running them now is because im having a smoking problem. that i have no clue where its coming from

yea ive seen a few people post about the ar's having that smoke issue but no one can figure out what its from though

i honestly believe its caused by the PCV valve being defective and staying open letting crank case "oiled air" into your turbos and thus creating smoke. my car is being taken in tomorrow

I, too have the AR 3" catless DP's ceramic coated.. they did NOT fit directly to the stock exhaust so I had a custom exhaust made to fit the DP's.. our car, too, began smoking just after install of the DP's and exhaust and there is a decent chance the PCV could be the cause and we will know soon enough as I usually reroute PCV and bypass EGR in all my cars so we will keep you guys posted as to the smoking remaining or leaving when I reroute our PCV.


and my wife's 535i is also white and we just did the amber LED angel eyes and the car looks nice like that... I like it better than the white ones as it makes you notice the front end more than the white ones do, IMO.

Thanks guys and yea my exhaust is the billy boat axleback so Im a little worried that the white smoke might start coming out if i put them on and the last thing i want to do is go to the dealer because the dealer where i go is absolutely filled with morons
