Hi All,

I have just swapped my old classic UK Turbo out for a 2006 WRX Sti Hawkeye Prodrive.

My old classic had a Hayward Scott exhaust with ScoobySport back box and sounded great.
The STi doesn't have that lovely burble which I miss terribly.

So, I've had a scout around the forums but seem to be getting more confused as to what I need to do...

The STi has a factory fitted Prodrive 340 pack, so do I just need to replace the resonator section with a straight through to get the burble through the Prodrive backbox or am I going to have to replace the backbox too?

Hopefully someone out there will know the answer

 

See how you get on with the deresonated section 1st if you still want more add the back box

 

I shouldn't worry it'll soon get a bit more noisy when the hg and ringlands fail.

 

I fitted a nur spec cat back to mine and it was pretty decent. Im running 3" decat downpipe onto the nur spec now and its a good bit louder.

 

Running a Milltek Catback and it sounds sweet...some burble but nice when opened up fully!

 

Thanks for the advice.
I think I'll try the deresonated section 1st as ScoobyReedy suggested.
Regards
