It does have a resonator fitted, i removed mine from my old 2006 STI it makes it a little louder but not massively.
The pic above has a non resonated pipe fitted and is not part of the PPP.

Yea none of that is a Prodrive system. To improve sound and performance remove middle section as shown by Don. And replace 2nd cat on downpipe with decat. Will still pass mot.

I've gone for a decat down pipe from Hayward and Scott for my foz STi. The rest of the exhaust is standard. Do you think it'll pass or fail the mot? Curious to know

FSTI has a classic exhaust layout (3 piece) with what might be a cat in the mid pipe as well as an expansion box.

Possibility of getting away with it the Don, what do you reckon? I've opted for it with the mindset it'll fail just curious and wishful that it'll still pass due to the centre cat and standard back box
If you just have the centre cat then it won't pass. The main cat is in the downpipe. Remove the centre cat and get one in the down pipe. Like sports cat.
