So, here's the deal...I have a 98 GTP that is bone stock right now.

In the next month, I would like to do exhaust, intake, pcm, and 3.4 pulley.

I have some questions, What mods do i need first in order to do a 3.4 pulley without breaking anything?

-Is it worth getting a downpipe when i do my exhaust?

-In lamens terms, what will a PCM do for me?


-Last but not least, this is my daily driver....are these mods safe if i drive civil?

-Are they safe to my stock tranny?


Any help or info/opinions would be appreciated, thank you
