Quick daft question - as most of mine are

Buying a totally standard P1 and do not intend doing anything to it (did lots to my MY00 and am fed up with adding bits here and there) apart from put Alcons on and change the backbox to something shiny

I've heard that the P1 upgrade backbox can be a bit "drony" which I could do without. I've just taken the PPP backbox off my MY00 and suddenly though "why not put this on the P1...?" Any reason why not? I can't think of one; it's only a backbox after all.
Not looking for performance increases - just something better looking than the standard Sti backbox.

 

Shoud fit no probs, i also heard they drone, but you can always try it, if you dont like it go back or sell your prodive back box for a scoobysport one or similar.

 

i have got p1wr backbox,it is slightly noisier than standard backbox but not in cabin,that is i have not had to increase my stereo volume! and it is a lovely noise

ps tsl have a p1wr box left over-see if you can try it out?!

 

I've got a PPP BB on my MY99 (no other PPP components) and it doesnt sound like it drones to me.

Would say not as loud as SS.

PPP Backbox is now on the P1...

Now then, is there any difference between the P1 upgrade 'box and the PPP box (apart from the writing on them)? Both designed to work with a front cat and catless centre...

I reckon they're exactly the same pipe

He was talking about the P1 WR Prodrive backbox, not the Turbo PPP backbox.
Completely (well slightly) different.
P1 upgrade bb has P1 stamped on it, and is louder than the standard PPP one.
