Performance, hence the brackets as it was cut to install. Then clamped with those brackets. Stock is a pipe from the downpipe all the way back. Also, the tips which appear to be on the newer version of PE for e92. At Least for mine.

You would easily be able to tell if it is stock or performance by the way they sound.

I looked at mine again and it says BMW performance, but I know the stock tips dont look like that. Does your driver side tailpipe have a valve in it? It's also odd that yours has the clamps on it.

Here is pics on mine, dirty i know

In my pic the vacuum hose is plugged into a metal piece that is essentially like plugging it with a vacuum plug.

No I don't have any hose connecting like yours :/

I feel like someone had something before and then had to put this on or something! I hope it isn't stock because I passed up on a good PE offer for today 😭

Here is a cold start:

Here is a cold start:
The hose is there on all 335i's. What I was pointing out is that it's not really used, there is just a metal rod that plugs the vacuum line. Yours may be plugged and stashed behind the heat guard. Does your driver side exhaust have a valve in it? Take a picture looking into the exhaust with the flash on. Also, take a picture of the driver side area where the hose gets plugged in my picture. I want to see if the valve opener is there or if it's just a plug.

I'm thinking you have a modified stock exhaust.

Has it really taken this many posts to conclude that this is a performance exhaust? It definitely is Diox. Those tips you have don't come on the stock exhaust

I remember seeing "boysen" on my stock exhaust. I bet they cut the exhaust out, modified the internals, put different exhaust pipes that allow tips, then used clamps to put it back on. The PE comes as two separate pieces and the center pipe requires a clamp. They may have just put straight pipes on the inside. If so it's better than stock!

I bet they cut the valve right off and put the pipe that allows tips to be added. I think we've figured it out. Btw, I could go back and forth for days. Just as long as I can help someone on here figure something out, just as I hope they would do for me. No matter what it is.
