Hi Hamish ,
Welcome ..
I agree with Pedro , PPP makes car pull a lot stronger , from lower revs esp. and adds a bit more "burble " to the zorst too
As for the price .. it's more or less the same from the dealers ... BUT .. don't forget to ask for ur 10% SIDC discount !!!!
Insurance companies work in different ways ,some recognise the PPP and some split it up as Exhaust upgrade , Chip management and 18% power increase , which will increase ur premium .. so fish around .
Hope this helps ,
Where are u ? Dont forget to go along to any of the local meets to say hello !
Cheers,
Steve
