I love a nice sounding exhaust. I just like it to sound natural.
You're not alone! This trend is so played out

2024 BMW X3M  [0.00]
Hello all I have myself a 2024 BMW X3M COMP with carbahm stage 1 tune, rk tunes front mount intake as well as catless downpipes from vrsf.

After install it seems my x3m is currently in limp even after having installed the angled bdg o2 extenders for about a week now. I have not enjoyed the vehicle yet after this problem has arrived. Last resort is to take the o2 extenders off and just have a check engine light as it ran better.

Please share anything thank might help thanks!!

Are you sure the power restriction is related to the o2 extenders? What codes are present?

I run BDG o2 mini cats (not the angled) and I haven't had issues.

Ohhh that's good info. Are you doing this to keep the readiness monitor set for the rear O2? I know in IL we can have 1 monitor not ready, wasn't sure if the rear O2 would show up as not ready, or not available though, with a tune.


On topic: Agree with Brock here, all the spacer is doing is emulating a cat in the eyes of the O2 sensor and the DME. The car doesn't know you have a spacer added, it just sees a voltage difference between the front and rear O2 sensor because of the spacer and thinks you have a cat. Maybe something happened to the sensors during the install of the spacers??

Yep exactly. I'm on my E50 tune and the car is showing readiness on both sets according to the scanner that I have at home. I plan to go this weekend and have it officially checked for emissions so I can report back.

HJS cats are incredibly expensive. Without even commenting on supersprint’s price there is at least $3k-$4k+ in just the cats. And depending on size a single HJS cat alone can be upwards of $3500.

Close enough. I still fail to see 2K in piping and welding. Also, why would they use HJS and not Gesi for example?

And I seriously doubt they're using the 1500 cats and not the cheaper ones
