OP OP! Article about the exhaust on BMW F23 230i Stage 3…
The stock exhaust was very dull, so we decided to add some bass and popcorn sounds.
During the modification of the exhaust system, minimal changes were made, namely the replacement of the muffler and the installation of a DOWNPIPE. When Stage 3 upgrades are done, the middle catalyst will be removed.
After the exhaust modifications, tests were conducted, and the result is that during relaxed driving, there are no resonances or unpleasant sounds, while active driving produces a very pleasant and not too loud sound.
PLANS FOR THE CAR:
We want to complete Stage 3, install water-methanol, and fine-tune it on the dyno.
