Does anyone know if adding the Apexi SAFC with a combo of a an Injen CAI - Cattman y-pipe - and GReddy cat-back is worth it. I know you will have more gain with the headers as well, but I might not add them.

 

depends on if you want alot of cool blinking lights .

With those mods don't waste the money if your on a budget, but if you got some extra cash to throw around go ahead. It is really easy to use

 

it probably is, read this

there is a nice 5.5 gen dyno on there

 

i think it will vary from car to car. There are tons of factors that would make a difference.

Only way to know is to get a dyno FIRST and look at how good/bad your Air-Fuel ratio is sitting.

However, from SR20DENs comments and dynos I've seen, VQ35s typically need one by how the VQ35s react to increased airflow from I/H/E mods.
