I have a billet 321t to go on to my car (widetrack blob), the car already has a prodrive sports cat, 2.5" tsl exhaust, fuel pump, panel filter.

I have purchased 800cc injectors

harvey (rip) headers and up pipe,

is there anything else I need to add?

Is an fpr neccessary? 3 bar map sensor? 3 port boost solenoid?

Cheers guys

I wasnt sure about the fpr, thanks for clearing that up

clutch will be done early next year, car has a prodrive sports cat hence the rest of the system being 2.5", if it needs to be changed I will deifnately do it.

I had same system on mine mate. Changed it wanted more torque.
Go full decat aswell.
What fuel pump have you got?

At the moment the car has a HRC 255 pump, which exhaust systen did you go for? Was the prodrive cat too restrictive?

Thanks
