I am so confused.
I am thinking about moding my xfire but everytime I read these forums someone has swayed opinions. What I would like to know is, will this Thomas Knight be like the turbos that I hear from other cars that give that hiss sound from the bypass? For some reason I love that sound and would be happy if this setup could do that as well:

I am looking into other mods, like ECU chips, ect... but would like to have this turbo installed first before getting any mods.

Thanks for those that contribute to us novice peeps.
