I did not take before shots however the stock sound is freely and easily available and im petty sure they all sound the same.
Before and after runs were made and nearly nil difference was noted. The figures it made is irrespective as im only using the dyno for delta changes.

I'm in two minds about the exhaust tips. The stock setup protrudes a bit however like the E46M3 I prefer to have it flush looking with the diffuser. Which is what I've opted for. What do you guys think?
