WOW, i installed the SOLO from smart madness. it sounds goooood. no drone on the hi-way nice sound in the city. sounds like a big cat purrr. very grown up sounding, that is what i was looking for. it was very easy to install, about 1 hour in the drive way. i also did the AFE filter from smart madness and the silicone intake pipe i bought off of ebay. the little thing is so much more responsive and it has much more pulling power.
smart madness is also great to deal with!!!
