This has not been tested however I'm pretty positive they won't. We will be making a few one offs pretty soon for the XI guys.

The price on the site is the lowest price available for the Catted version. This is the preorder price. Thanks!

No. It is a minor change we have to make to have them fit. We will have the catted and catless available at the same time when we make these changes. Thanks!

Keep on the good work, guys ! What I have seen from your products so far is high quality for a good price, parts that I like to use on my BMW. I am looking forward to your catted downpipes as I expect many of us do.

Our initial payment was sent yesterday for our cats. We paid for the first 50 cats (25 sets) which will be done in about 2 weeks. After that, its off to work and get all the pipes finished. This takes about 2 weeks. We'll get the set out to you Eugen!

Looking for just a few interested in these and we'll go full production. Also, the local XI owner that lets us fit them on his/her car gets a free set.

Great question. BMW cats are not high flow. They're extremely restrictive and do not give proper flow through the exhaust. These cats are true high flow cats and still offer the 3 inch piping like our catless. They will taper down to 2.5" so they will fit ANY aftermarket/stock catback system. Thank you.

My first post here, and I've been reading and learning a lot.

But my question is if they go from 3in to 2.5in... isn't the 3in a waste??..because once it hit's 2.5, it's restricted?

Thanks.

No waste at all

The 3" piping allows quicker spool out of the turbo. Along with the inlet of the Cats which are 3" as well. Since they taper smoothly to 2.5", they start the spooling extremely quick and will fit any aftermarket/stock catback system. This is the only 3" catted system on the market and will make a ton of power. We will try to get all the dyno's finished tomorrow.

Adam,

Will they fit a right hand drive E90? If so then I'd be very interested in a set here in Aus.

I'm not trying to be a tool, but you have been saying that you will have dyno's up for a month already. How much longer until you get your booty's to a dyno? Better yet, what's the booty dyno tell you? Faster than OEM? A noticeable, healthier spool? More turbo WHOOSH?

I'm with ya. Sorry we couldn't get the car to the dyno, but we've been doing a ton of R&D with the car the last few weeks. We should be able to get the dyno's finished today (Wed). We'll keep ya posted!
