Quick question, I have an RB320 but is is so quiet compared to my 05 Sti can anybody explain why this is?

Im not 100% sure with the RB320 but the hawk eyes have got equal length headers on them which makes them quieter.

The exhaust is homologated to EU rules for Supercars. If you want it noisier replace the centre section with a straight through pipe.

Will replacing just the centre section make much of a difference?

Could have sworn it was said this was only true on JDM's

As for them being quiet, they are indeed, my 07 WRX is too.
As I have said on another thread though, I want something really subtle and not a screaming, alarm triggering jet fighter roar.

What back box was that running through?

The first sound file is the PPP exhaust same as RB320.
The second is with a straight through centre section, you can hear the difference right? My laptop and microphone were 6 feet away and 2 feet to the side of the back box. Obviously the further you get away the quieter it will be. If you have a PPP or RB320 you will be able to associate with the before file.

The Backbox is the Prodrive PPP box. It is now very Dugga Dugga.
