Hi folks,

I have a totally standard MY01 WRX, and a nice shiny Prodrive back box waiting to be fitted ... but should I wait until I get an ITG panel filter before having the back box put on ?

I can understand how the less restrictive exhaust will want more airflow from the front, but can't see that it would have enough effect to make something go bang in the meantime...

Opinions, please

 

Its perfectly OK to get your bb fitted before your air filter.
You wont see any downsides only a nice growl when you push the pedal.

After a tenner to the chap with the air gun and lift, the box is now on, and I must say I rather like it

Pity the nearest tunnel is 30 miles away
