RM520 directly from works or car workshop/performance workshop? If the power improves at 3k rpm..I think it's still quite suitable for city drive...coz I usually switch gear at 2-3k rpm. But the noise might really be a prob...better insulation on the firewall maybe?
I'm actually thinking of either getting drop in knn...then I saw this cf filter and it really looks nice n sweeeeet
