Does anyone know if there any difference between an exhaust of a WR1 and the exhaust from a PPP dealer fitted pack.
As I am am upgrading my std exhaust, on my MY03 STI type UK and I have been offered a WR1 exhaust and it was the prodrive PPP exhaust I wanted, if there is no difference i'll have WR1 exhaust.

there isnt in terms of fitment, and as far i know the parts are the very same....

should be fine

 

The WR1 and PPP exhausts are the same(ish).
Early PPP exhausts had a different sports cat downpipe with split exit.
The main exit pipe doesn't line up very well with the turbo exhaust vanes.
Late PPP and all WR1 sports cats have a single cast bellmouth with a divider which allegedly allows more power.
The rest of the system is the same for decat and 1st part decat centre section.
Go for the WR1 exhaust.

The wr1 exhaust I have been offered doesnt have the down pipe though! will it be any use and will I notice any difference with my std sti downpipe. Or will it not be worth buying on its own?
Should I be looking elsewhere

 

all youd get in effect then is a centre decat.....which wont do much...and a better backbox, which sounds nicer....if its cheap then do it....if nto then dont...

 

As Neil says, all you're being ofered is also found on the WRX PPP.

S/hand prices for the box are about £170, the decat is about £90.

Being from a WR1 means nothing so don't pay a premium for it.
If you are offered the d/pipe then get it. It is MOT friendly yet flows as well as any good decat d/pipe. S/hand price should be IRO £225.

Thanks for the advice guys.
Not sure what to do.
Might buy a full miltek system instead but that will be later in the year.
