By no means are any mods Needed but it is always nice to have the supporting mods. But first what year V6 do you have that would hep us to know if you can even do a swap to Long Tubes.
If i was going to do an install on my car i would start with some BBK long tubes paired with 2.5 inch mid pipes with my V2s. Then i would upgrade my breaks and suspension then i would do the little motor things like the Ported Manifold and thorttle body, spacers, etc..
