This intake is great! I love it. It seems to have added power all over the rev. range and the sound is great, really aggressive up top and un-noticeable over the Stromung down low. The combo of the two sounds is wicked! It pulls smoothly and hard (much like a V6) to Red Line now, no more pull then a kick, as it hits 3500 to 4000 rpm like it used to. Seamless acceleration like a stock car, although much faster.
