Milltek louder?

[Jordan1.8t]

As the title says guys!

Can i make my miltek louder at all?

Or should i go buy a blueflame catback? Would the blueflame fit
My milltek dp?

Is a non resonated system? If not, take out the middle box, will make it a touch louder

a downpipe and decat will make it louder
