dram300 Posted September 13, 2008 Share Posted September 13, 2008 (edited) Anyone know what the exhaust mods on a PPP'd MY05 WRX look like? (I'm talking about the the CAT mod, not the back box (clear Prodrive markings)) I got the impression from various sites that it was a centre cat delete pipe on the WRX, i.e. straight run, no bulges, however looking at mine, it looks like it has a CAT in the middle. Anyone got some pics? Edited September 13, 2008 by DRAM300 Link to comment
bogie Posted September 13, 2008 Share Posted September 13, 2008 Depends if it's the 2.0 or the 2.5. 2.0 has a straight CAT delete, but the 2.5 has a stinky little silencer in there instead of the CAT, something to do with noise regs. I have removed this stinky wee silencer and the resonator and it sounds soooo much sweeter, although still not as good as my 2.0 sounded without any post PPP mods. Cheers Link to comment

I'll take a pic if it stops raining for a minute Cheers Link to comment
dram300 Posted September 13, 2008 Author Share Posted September 13, 2008 Any of these look familar? Downpipe from Engine Bay PPP CatDelete from Drivers Side? PPP CatDelete from Passenger Side? CatDelete-Center Join CentrePipe Backbox clearly stamped Prodrive Link to comment
bogie Posted September 13, 2008 Share Posted September 13, 2008 The CAT delete isn't stamped Prodrive (it's made by Scorpian I think), they also refit the heat shields to the centre CAT delete. If you can get a peek through the opening of the bulgy bit, you should see the straight pipe going through with no CAT. They also have a boss fitted to the CAT delete pipe to take the lamda sensor. Looks pretty much how my 2.0 looked. Link to comment
dram300 Posted September 13, 2008 Author Share Posted September 13, 2008 Cheers mate, makes sense that they would refit the heatshields. I had a look at no end of websites today, fair to say there isn't a lot out there on PPP. Thanks Link to comment
iain01 Posted September 13, 2008 Share Posted September 13, 2008 think the newage 2.0 wrx ppp, still has the cat between the downpipe and centre section, think it was only the 2.0 STI ppp that removed that cat. Link to comment
gus the bus Posted September 13, 2008 Share Posted September 13, 2008 (edited) The cat pipe is removed in the WRX too. Just looks like it is still there as the heatshields are replaced around the decatted pipe. Also the centre section isnt a cat its just a resonator.

Had a wee roll under the car earlier on and got to wondering where my decat pipe was. Good to hear its disguised as a cat-pipe !!! Link to comment
