What downpipe is this?

john6552 · 11-29-2016, 04:09 PM

I was trying to buy a replacement stocker for my 2011 335i and got this. It does not match mine but the guy says 2011 335i is what it came out of. I tried searching but didn't come up with exact pictures or descriptions of what I'm looking for.

The bungs don't line up with my 2011 335i downpipe though. Here was mine when it came off. See how off the bungs are? I wonder what is different?

The right one is what came off? Did you already have an aftermarket DP? Your post makes it sound like you have a stock one (or thought you did) and wanted a replacement stock one. Left one is stock, right is aftermarket with a dump. O2's are on wires, their placement doesn't have to be EXACT.

Sorry I should not have included the aftermarket in the second pic, that made it confusing. The stock DP in the second picture came off my car a year ago when I upgraded to aftermarket, and I sold my old stock. I am now trying to buy another stock downpipe that will fit my car. I bought the downpipe in the first picture on ebay but the o2 sensors are in the wrong spot and the shape looks a little different so I am wondering if it is off the wrong year. Are you saying it should still work?

I think I figured it out. Looks like this was off a 335xi. The aftermarket n55 downpipes will all fit a 335xi because there are no brackets but the 335xi stock downpipe will not fit a 335i due to bracket issues. Thanks for the help!

It also makes sense that it is smaller and the Xi has secondary cats.
