Fitted the Scoobysport Backbox recently, I'm quite surprised at how quiet it is.
I was expecting it to be much louder than the Prodrive BB, but it's not that much louder.
Think I need to swap for a really loud one.

Don't really want to make too many changes yet, as I'm waiting for the PPP.
So how come a replacement downpipe makes such a difference then?

I only found this out after about 6 phone calls to them.It seems strange that a company that sells 4 different types of exhaust only advertises 1 of them.Personally i`m happy with the 1 i bought,but some people might want a louder sound, should be given the choice!!!!!!!!!!!!

I have the "quiet" exhaust, and i can guarantee you it's not the same noise as standard!
It's pretty quiet on tickover, but full booting with a decat DP (standard centre) produces a nice noise.

Change the center section, and also the small cat after the down pipe, both mine and a friends STi7 have both got straight-thru centers with aftermarket backboxes and the sound is much better, the resonator in that section swallows up a lot of the scooby throb.
Dont do a full decat tho, not if you want to keep your warranty.
