Hello everybody,
Want to up change the downpipe for a more high flow option but still have a CAT. On reading other threads people have suggested using an STI8 PPP down pipe on my MY01 WRX. Is the standard STI8 DP the same as the WRX one and how can i tell what an STI PPP DP is. Reason is i am a cheapskate and doing a DP change this way could save me some cash.
Yours
Peter

 

anybody? please

 

WRX-STI share the same downpipes, you read about the PPP STI downpipe that is much better and recently has different (open neck with splitter) design from the following:
