    can you tell the difference sticky? Click here to enlarge sound-wise. the n54 in the video is suffering from the dreaded wastegate rattle. so if you can tune out the annoying ticking upon decel and idle, tell me which exhaust pitch you prefer?

    I'm a bit surprised as to how good they both sound.

    straight 6's are hard to mess up Click here to enlarge although ive heard my fair share of raunchy, ricey sounding x35s. of course pitch is subjective but bmw got it pretty well, the perf exhaust is just section 3 no?

    Yes, I believe it is just rear section.
