I have the 2.5" Trubendz kit and I'm loving it.. The only problem with it was a small fitment issue, but that was resolved by simply installing CFM poly-urethane bushings.. As for sound, I got a HFC and resonator on it.. It's still a little loud because of my header but it's got a deeper tone than some other Trubendz kits I've heard.. Good luck in your choice.
Trubendz also recommended to use 2.5" if a header was going to be used.. He said 2.25" should be used for a car without much mods at all..
