hey guys,
later next week I will be fitting some Procircuit T4 pipes to the xtx. One of my pipes (the one with the sensor) is badly damaged.
The workshop who will be fitting the pipes will knock me up a set of headers as well. My question is can they leave the balance pipe out?

is it really needed?
the T4's will be straight through so may be a bit loud but thats fine by me.

has anyone else done this on a set of loud pipes? does the sound sound any different or did you have any problems?

thanks guys...
