i love these threads and breakdowns, thanks for sharing.

i do have a few questions;
1. does the full Akrapovic Evolution titanium exhaust system delete or replace any catalytic converters and/or trip any check engine lights? (basically, is it cali smog legal)
2. does bmw put up a fight with warranty claims with under drive pulleys?
