Does AR manufacture catted versions ? That is news to me :-)

I have stock exhaust with mine and will notice a very faint smell on startup - so minimal I wouldn't even consider it an issue.

Sure they do. There is one for sale currently on the for sale threads! Decent price for used. Maybe you can chew him down a little bit

Correct me if I am wrong, but 3" dps on an XI requires you to drop the engine (well the rear mounts). Much less of a DIY than the standard RWD models.

drop the subframe and raise the engine a little bit, its a more complicated install compared to the "i " model

and it doesnt matter what size dps you are installing, that work needs to be done just to get the stock ones out

XI for sure... You missed out on mine I sold last week Altec... I sold them for a steal to a local guy. AR is the only way to go!

No need to drop the subframe. We accomplished an install and an uninstall with out doing this. SImplest way is to disconnect the tierod and a few of the suspension bits and push the wheel out so you can get the pipes in/out.

PM me if you'd like help, we did mine in 2 hours on a lift so I have some good feedback on the installation and removal.

Holy shit...makes me even more happy I didn't get XI lol

Links to AR catted for xi anyone?

[bamsefar]

I just checked the aR web site, there is still NO catted xi downpipes available for 335 (E92).

It is available for the 535xi though - but I have a 335xi ;-)

+1000

XI fitment is tight and the ar design pipes maximize the available space to the max and fit like a glove. For an XI these are the only ones I would consider.

There are no ar design 335XI catted pipes as there is no room.

We are a distributor for AR design now, so if you want you can make it easy and just take care of everything all in one place

[bamsefar]

I wonder if it is possible to replace the downpipe + secondare cats = one solution with race cats in place. The goal should be to make it possible to dun better downpipes without any 2.5" restriction all the way to 2nd cats. And then replace the 2nd cats with high performance race cats = close to the best and still pass emission checks ?

I have the Ultimate Racing catted downpipes and AE catless exhaust. I'm happy with the setup. No smell and no check engine light. Some people have complained about rust, but after one winter, mine are holding up fine.

Whatever you go with, be careful with the O2 sensors. It's easy to damage them.

The man speaks the truth!
I've installed a set of ceramic coated AR downpipes on my '09 XI, and I managed to switch the 2 front 02 sensors around... Not a lot of fun. The install was a PITA, but worth it. You will not regret them if you go the AR route, fitment was perfect!

You went with a good choice...try doing UR cat less pipes and finding out they fit so horribly you want to kick yourself for having to put it all back together and do it AGAIN a week later

God... I couldn't imagine having to do that again... It was a total PITA. I'm glad I chose to go with the AR pipes. I would recommend them to anyone.
