I decided to risk fitment issues and decided to buy the Active Autowerke Catted DP (Sku# 11-065G). There are very limited aftermarket parts for our cars but majority of the 330i aftermarket parts can fit the 330e. You might need to make some modifications or adjustments to do so. This case is the same with this downpipe. I know 330i cars with a production date of 9/2020 and later have downpipes with two brackets lining up in a straight line so they need the AA dp with the sku# 11-065G. Which is what I got.

The installation was challenging because 1) I didn’t have a lift and my car is lowered, 2) The two brackets on the AA dp do not line up with the car’s dp mounting bracket. After 4 hours, I was able to install it without having to use the brackets. The dp sat in perfectly, lining up with the turbo and the exhaust and there is no movement at all once it was clamped up. However, the bottom end of lower O2 sensor is hitting the mounting bracket. I wished I took this off before I installed the dp but I just wanted to get the install over with lol. So if you decide to buy this dp and you have a 330e, take the car’s dp bracket off if you can before mounting the dp. I’m just glad I didn’t have to cut anything like I did when I installed the MST intake. Which I sold because it didn’t do anything but make nice sounds lol. Used the money towards the dp.

The sound is just a little louder than stock which is what I like. I can actually hear little burbles with the windows down. I did a 3rd to 4th gear pulls and everything looks good. It definitely pulls harder than stock and holds boost much better. It’s holding about 2 psi higher on both gears. And so far no CEL.

Here is a video from inside the car, windows down and up.

Pics of the dp, inside the engine bay showing the dp bracket not being used and the bottom end of the lower O2 sensor hitting the bracket. Jb4 log pics of 3rd to 4th gear pulls. Before and after dp install.

I did 12.73s from 100-200km/h compared to a 13.06s before installing the dp. The dragy was invalid showing a negative slope on the 12.73s run but both runs were actually on the same road and it’s actually on a bit of an incline. Once I get another chance, I will be doing a cleaner run but I’m pretty sure I will get the same result and maybe even with a better time.

Sounds good. Not bad for the heavier 330e.

100-200 in 13.06 is really good with just a JB4, my stock 330e does 15.98 which is in line with other 100-200 times I've seen for the car stock. Some questions if you don't mind:

- A or B engine?
- What JB4 map are you running?

- B engine
- Map 6 additive because absolute map does not work for me. Below are my boost settings.
- I’m also running one step colder spark plugs and 20% e85 (E20).

Also, after doing many tests/runs, I get the best results when I paddle shift at 6k rpm into 4th and 5th gear. And shifting at 5.5k rpm going into 6th. I usually start on 3rd when I do these 100-200 runs.

[330eJL]

I realized I didn’t update this thread with my best 100-200 time. But I managed to get 12.47s at cooler outside temps. Slope is negative but it’s similar to the slope when I did 12.7s.

Thanks a lot for your reply. For the 100-200, I just go to 90kms/h and put it in Xtraboost and the gear to S and push the pedal down, so I can compare better between runs.

I have a A engine and have been told by a tuner to not go over 18psi (by default it boosts to 11-12) so I will try to keep the additive map under 6psi so I could divide your map by 1.3 to have my values.

Those B engines are really nice, pity we don't see them in Europe in 320i or 330e since mid 2020 or so.

*UPDATE* Alan from AA reached out to me and asked me to send them my stock dp so they can make adjustments on a new dp and will ship me a new dp with the adjustments to fit my car. They sent me the new dp so fast, the only thing that took long was me finding time to install the new dp. When I did, it fit perfectly. It took me only 2hrs to get the new one installed.

I am not sure when BMW started changing the dp brackets for g20 330e but it might be at a later date. Mine was built 9/20 but it still has the V configured brakets. I think best way to find out with a g20 330e is to look at the bracket that holds the dp. If you look at the rear O2 sensor and it is between the triangular opening of the bracket, then your dp brackets are the V-style ones or configured in a V shape. You would need the one with SKU# 11-065.

Below are pics of the first AA dp I installed (left) next to the new one I recieved (middle) and the stock one (right).
Also pics of the rear O2 sensor sitting between a triangular opening of the bracket that attaches to the dp brakets.

Thanks to Alan alan@activeautowerke. He reached out to me offering to fix the fitment issue without me even reaching out to them. I actually didn’t care about the bracket issue and was just happy I was able to fit the dp that isn’t designed or made for 330e. And the gains I made out weighed the minor issue. AA didnt have to reach out to me but they did and went out of their way to fix a minor issue. Shows they care about their customers.

Hello 330eJL , it seems like the new DP is Catless downpipe, right? How was it compare to previous one and stock?

My car is 530e (same engine B48B and e-motor) + JB4 Map6 which is very close to yours. Now I'm deciding to change stock DP to catless downpipe but a bit of reluctant because my car cannot be tuned only JB4 I can do.

I saw your JB4 graph which pre-boost increased around 2psi. I guess it increase the ecu_psi, right?

Can't wait to see your feedback

330eJL Why did you change to one step colder plugs? Does it make any differences? I'm thinking about it too

Both DP are catted and they definitely make big difference. Yes it increased boost to about 2psi. I love the sound. It burbles a bit, specially when the engine is cold. It may not be loud enough for some but its perfect for me.

Timing got a bit better with colder plugs. Alot less timing drops through out the gears, but I also run E20. I recommend running both if you have access e85 and you want to up the boost by 7psi+ I can only run an additive Map because absolute maps dont work for the car. I really wish it does because I think I can run much faster times. I also found that running higher than e25 maxes my fuel trims so I just run e20. This is with the additive map I run, not saying the car can’t run more than e25. Maybe with a custom tune you can. Jb4 is just limitted, specially with these cars. But for the money and what is available right now for these cars, i think its worth it.

330eJL Did the latest DP one better than previous? It seems like has less cell (more flow).

May I have your colder plug model/part no.? I interested in the change for better timing too. DP and colder plug are my next mod


For JB4, Have you had this situation like me? During gear 3-4 and beginning of gear 5, ecu_psi usually not more than 6-8 psi but but some points/some times ecu_psi shift up drastically to 12, 13 till 17-18psi. I can't find what is logic of DME. It seems like this happen to G20 330e and G30 530e only.

**I run E20 fuel.

6,000 | 5.9 | 40
6,500 | 5.1 | 40
7,000 | 4.6 | 40

Have you ever tried other setting than above setting? Such as PID gain, FF, Fuel Open Loop.

Yeah those boost spikes towards the top end of the rpm are weird. I’ve never experieced those. I see spikes at the beginning after gear changes. How’s your timing and fuel trims during those pulls?

I’ve experimeted PID, FF, Open loop specially when I had the MST intake because I was running lean and actually got a bit slower. I was trying to tune for it but nothing helped lol. Plus I am very new when it comes to tuning. Taking the intake out and leaving everything the same other than the boost settings works the best for me.

Here it is for timing and fuel trims. What do you think?

I also have MST Intake too
Oh, you got drop of performance then get back to stock intake, right?
I haven't compared the graph with MST and stock intake yet.

the timing looks fine from what I see. Do you have the excel file from Jb4? Also I measure performance using a Dragy. With the intake, my 0-60 and 1/4 mile times were slower no matter what I did with the map. The graphs looked fine other than I was running lean. And at first I thought the car was pulling harder until I started measuring with the Dragy. As soon as I got rid of the intake, my 0-60 and 1/4mile times were back to where they were.

330eJL Please check my JB4 excel files here.

MST thing surprise me (in a bad way). I'm thinking about measure with Dragy and try the stock intake (and Dragy) to compare.

Here are dragy results. 1/4 miles and 0-100kph.






Actually, I had got 1/4 miles for 12.91s and 0-100kph for 4.78s but with much higher boost which I think it was too much and not safe.

Those are good times. That was with the MST intake right? Most say the MST intake do not yeild any performance gains and some
say it does but very minimal. For me, it made my car a tad bit slower lol. But that can be explained by environmental factors not the intake. I didn’t have it on for that long. Do you have any 100-200km/h times?
