So basic question I've got a Milltek cat back an I'm looking to get a decat pipe added just unsure if I will need a remap or will the car still act the same without an just add extra niose ?

Currently have the cat back with Hks induction with a flashpro group n map installed

Ideally needs mapping to be sure of safety and to make gains but...

Without changing the exhaust manifold itself gains will be minimal. You need an aftermarket manifold and sports / de cat.

Would recommend a remap as you don't want to be leaning the AFR out
