I'm looking to get AR design downpipes for my 2009 535i xdrive. Everything is stock right now only comestic mods so far. I wanted to know what would the ar downpipes do for me with stock exhaust? louder exhaust note? more power? im always running 93 octane. also wanted to know what is the difference between catless for 1099 and with race cats for 1349? thanks in advance!

AR Design are the best dp's you can buy. With a stock exhaust it wont be louder, you may hear your turbos spoiling a little more but other than that, nothing much. If you have to pass emissions test, I would go with the race cats, otherwise you'll have a CEL. Catless gives a little more performance due to less restriction.
