I got some question and advice.

I got some question and i need advice!

I installed greddy tic about 6months ago and i want more mod on

exhaust. that was my first mod for my g37.

I think i have many choices but i couldn't decide. If i want to better sound

and louder sound, what should i have to install HFC or Y pipe?

Also which brand would you recommend? or other opinions?

federally, non-oem cats (including HFCs) are illegal unless oem is no longer available. in california, non-carb intake/exhaust parts are illegal from what i understand.
