Can anyone advise as to how much of a noise increase you get from a de-catted down-pipe on a MY00 with a PPP fitted.
I used to have a scoobysport back box fitted and the noise increase from that was great but about my limit, i now have the Prodrive backbox which was fitted as part of the PPP.
What kind of performance increase can i expect form this mod ?
Is it worth it??
thanx in advance

It depends which one you go for.
The BPM is very quiet - although you lose low down spool up.
The Scoobysport - certainly the one on my car - is about 6db noisier than the BPM - enough to make me have to run an extra bung on track.
Quietest will be ported headers with BPM - this is a very quiet combination.
