Prodrive exhaust diameter ?

MY 03 STI (PPP)

Am looking to replace PPP downpipe (highflow CAT) with H&S decat downpipe.

Can anyone please tell me what diameter I need to meet with PPP centre section. 2.5 or 3 " ?

Thankyou.

It's 2.5"

Can I ask why you're thinking of changing it?

There is no need to replace your high flow cat with a decat downpipe, unless you want to splashout another 700 quid for a remap? as the high flow cat is as good as the pipe your replacing it with.

Re-map booked with Bob Rawle v.soon and more people talk of benefits with de-cat (other than MOT) than not. Can anyone advise differently ?
