Great thread...thank you for the info.

Do you think the BMS Stage 1 (no downpipe) solution would work on the new 240i as well? I wonder...

I never recommend plugging in a tune that has not been tested and approved by the manufacturer

With all those supporting mods you should definitely go with the jb4 stage 2 to get the most out of your car.

I was just looking around at what's out there and noticed the Dinan tunes don't recommend a downpipe, no matter which tune you choose. They recommend their exhaust, but isn't that just a cat back? Am I missing something here? Wouldn't a downpipe be require like OP says?

I guess your first mistake was taking advice from dinan lol

In all seriousness though, it is probably because of being in CA and emission laws that they cannot endorse anything related to replacing the cat.

That makes sense, thanks.

And no not brainwashed. Simply looking at what's out there before making any decisions.

just read this - had a 235i for a month now - I already had the JB stage 1 from my N55 on my previous 5 series.

question is can I run the JB stage 1 with a 200 cell DP?

don't want to waste the JB stage 1 and have to spend on JB 4
