My, much loved, '04 G35 sedan was taken out by a lady who ran a red light, I now have an '09 G37 Jouney sedan. I did the coupe mid-pipe and straight intake on my '04, are these mods doable on my '09? I don't want to do a full-on aftermarket mod on these systems. I really liked the subtle sounds that I got out of my '04 mods.

Thanks in advance.

ps. I have an un opened intake spacer for my '04 that I never installed. Respond if interested.

The '09 is a dual TB configuration so nothing from the prior generations ('06 and older Sedan or '07 and older coupe) will work. I'd suggest looking into Stillen Gen 3 or R2C intakes.

I did the "coupe mid-pipe mod" on my '04 sedan; can I do the same thing, with an '09 coupe mid-pipe on my '09 sedan?

There is no difference between the '09 coupe and sedan mid-pipes that will give you a hp increase that I'm aware of.
