Noooo.. catless way to go 
Its okay you'll be fine
My installers got them in. Was a nightmare, there just tricky. Gotta put them in at the same time! Literally took 8 hours though. I think if I want them in they'll get damaged on uninstallation. Maybe like break the weld and then reweld it back together after. I'm definitely selling these with my car.
AR could make you wait FOREVER! I ordered through Modbargains so they put more pressure on them. If your an individual buyer it could take some time. Dude if your doing this with a TUNE the downpipes are wild. Real nice upgrade. Running 15PSI and I'm HAULING ass. cant wait for COOL air

I'll see if I can just keep calling ar design and see if they're able to get me the downpipes sooner rather than later. I've already paid ar design, so it's now a replacement process.
Are you able to run 15 psi with just 93 octane or you running something higher? Yeah, I've already got the JB4 and DCI's installed and am VERY happy with that. Finding an intercooler upgrade for the 5series is tough though. :-/

ugh... I don't like these stories about how hard these are to install. I wanted to do it myself.

Just throwing this out there unless you have a after market exhaust then getting downpipes makes no sense since the stock exhaust diameter would be restricting, so anyone thinking about dps get a 3" or already 2.5" exhaust first.

Looking at the performance improvement you're seeing/feeling, do you have an upgraded exhaust as well as the dp's?

AR DOWNPIPES INSTALLED! Wow what a bitch, I dont think they'll EVER come out but wow what a difference! I havent even retuned the map yet and this think is BEASTLY. I think after the tune I'll be flyyinggg... I really felt bad for these guys installing. It just wouldnt go in one at a time, you had to put em both in. The whistle sounds nice after I shift each gear. Its such a sleeper I love this f-ing car. Thinking of intercooler still but havent really overheated. Car runs like balls in the heat though.
Ill post a vid soon

No company unfortunately manufactures intercoolers for 535i at this time due to the way the front of the vehicle and other components are setup, theres either a oil line or power steering line blocking the installation of a FMIC. Unless you get one custom made you are pretty much SOL at this moment, but who wants to spend close to 2k for an intercooler. The thing that really annoys me is the fact that the 335i stock intercooler is larger than the 535i stock intercooler, which really makes no sense considering how much larger of a vehicle the 535i is.

The only person I know of that has had a intercooler recently fabricated is TLO03.

Oh and ofcourse this dude but his setup was ridiculous.
