The kidney shape resonator, apparently was designed to minimise the noise over everything else. I was told that by removing and replacing it with a 3" mandrel pipe, my car would experience better performance in terms of acceleration. The noise is something I reckon I could enjoy during urban driving or short runs on the highway. But am not sure how loud it gets at mid to high rpm or at constant high speed of about 160 - 180 km/h.Anyone can shed some light on whether driving at a high speed for long periods is tolerable and whether there is vibration?</blockquote>
