Hey guys,

So I have AP with a Depo HFC and a grimmspeed 3port in the mail.

I have a couple leads on catback exhausts so relatively soon I will have the HFC and Catback.

When I get that all on there is it safe to run the Stage 3 map without an aftermarket DP on there?

In the mean time I plan on putting on the HFC and running the stage 2 map.

My overall plans for the car is nothing to crazy.
This well probably be it for go fast parts.

I'm also going to assume to install the HFC I'm going to need 2 exhaust gaskets.
Does anyone know where to pick those up?(Or will standard 3" 2 hole gaskets work)
