you can get a K&N FIPK for an intake. i have that and it sounds so good. also im dropped on Tein Flex w/ Edfc. they ride like stock on the softest setting but on the hardest it is a kidney shaker. i've got a Greddy Ti-C Dual and it sounds good and doesnt drone. but if youre looking for a single get a J's 60rs. my J's 60rs is coming in 2 weeks and its only like 12lbs. the sound is also pure sex. but with all single exhausts it is gonna be a little loud unless you get the T1R 70r-em or Asm.
