Nova is ok. Shark's also not bad. RDLogic perform very well....there are too many pipes,you may need to try
I only have problem with LD3's stock pipe(come with box).abnormal back pressure and hard to adjust.Also it is a bit too long so fit for small tight track.Some people use it and feel not enough top-end,so just lean it and lean it till....engine die.Then blame STS suck....
