Hi all
Would i need to remap my 2005 ppp if i only replace the 2nd cat, keeping the 1st downpipe cat??
Would prefer to fully decat but had hours cut at work and looking to save on cost a little
Thanks for any advice

 

No. Wait til you get it decatted then remap. Bob

 

If it is a PPP, then it already had a 2nd decat. If its a WRX, then your next step would be a sportscat downpipe, decat uppipe and remap, but you'd be looking at around £1k for that.

 

Should just have the sportscat downpipe in place.

 

If its an STi, yes.

If its a WRX, then it will have the std up and downpipe cats.
