SilverLS400

I am thinking on going to an aftermarket setup, the problem is i dont know which route to go........I want a nice deep sound when crusing and the same when i floor it, i dont want no farting and poping noise like these hondas, remeber i got a lexus here,
my next problem is what size tip will look good on a 90 ls??? I always like the remus style tips, dtm or something. I just want the sound and looks, should i go full cat-back or what?? will i notice any hp gains what so ever.....i strictly cruise so i donnt all this hp gain.......
