I like the tune a lot. The car runs smoother and adds approx 15 hp, plus you can delete the cold start if you want, increase RPM and top speed limits.

ESS has designed a tune for the E9x platform, but tailored for specific exhaust options:

1. Stock
2. High flow cats
3. Catless
4. Akrapovic Evolution system (the tune I have).

From what I can see in your pictures it appears you have stock cats, and only the resonators were removed. You have the Akrapovic Slip-on/cat-back exhaust, not the Evolution system. You might want to share pics further up in the exhaust so we can see if you in fact have the stock primaries.

So to answer your second question, you may benefit from the ESS tune but when ordering choose the stock exhaust (once you confirm you have the stock primaries).

Hope this helps.
