Exhaust/remap question

[AlexBurns1]

Still looking for a 182/197 or 200 cup, the first thing i want to get done is the exhaust with decat which spits and pops, can anyone tell me which would be the best exhaust to go for? and remap's do they go with exhaust and are there different types you can get?
Thanks guys

Not too sure on the exhaust but you can pick up an RStuner off here and have the overrun map. Someone correct me if I'm wrong?

What does a rs tuner do?

I would decide which model you want before an exhaust.
Thats three different price brackets.
