hilli182 Posted February 27, 2014 Author Share Posted February 27, 2014 It must be decat or it wouldn't have "not for road use" engraved on it with the part number though .... Quote Link to comment Share on other sites More sharing options...
hilli182 Posted February 27, 2014 Author Share Posted February 27, 2014 Also just Googled the part number and it comes up on various sites as cat by pass pipe or decat depending on the site Quote Link to comment Share on other sites More sharing options...
BlackBosh Posted February 27, 2014 Share Posted February 27, 2014 the turbo back i've bought the down pipe is one piece replacing the first and second cat, like thisGD SUBARU IMPREZA WRX STI EXHAUST DOWN PIPE DECAT 01- DP7650 I think the 2nd decat pipe looks like this if you were to keep the cat in the down pipe http://www.ebay.co.uk/itm/Subaru-impreza-wrx-sti-2nd-decat-pipe-exhaust-/161233031168?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item258a3cd000 note the angles are a lot sharper however you would still have your standard mid/intermediate pipe in place and then the rest of it is cat back i.e. the pipe you are looking at and a back box hope this isn't more confusing Quote Link to comment Share on other sites More sharing options...
quit Posted February 27, 2014 Share Posted February 27, 2014 You got 2 cats technically , you get a decat downpipe then a centre pipe , that has a resonator to try quieten it down a bit but don't work like a cat 1 Quote Link to comment Share on other sites More sharing options...
BlackBosh Posted February 27, 2014 Share Posted February 27, 2014 Not sure now maybe if the angle the picture is on was different it would be easier to tell. and the engraving could be to do with noise as well Quote Link to comment Share on other sites More sharing options...
quit Posted February 27, 2014 Share Posted February 27, 2014 I have a similar pipe on mine but no resonator Quote Link to comment Share on other sites More sharing options...
BlackBosh Posted February 27, 2014 Share Posted February 27, 2014 Nope I've made my mind up in my non-professional opinion that is an intermediate/mid pipe you are looking at not a decat pipe lol It will still fit though Quote Link to comment Share on other sites More sharing options...
quit Posted February 27, 2014 Share Posted February 27, 2014 It is a decat pipe Quote Link to comment Share on other sites More sharing options...
hilli182 Posted February 27, 2014 Author Share Posted February 27, 2014 I think so too because it looks the same as other decat pipes just with the res box in..... If it was just eBay listing that said decat then I'd be weary but having Googled it loads of sites say the same as the ad Quote Link to comment Share on other sites More sharing options...
quit Posted February 27, 2014 Share Posted February 27, 2014 To fully decat you need a downpipe too Presume a 2.5" system ? Quote Link to comment Share on other sites More sharing options...
hilli182 Posted February 27, 2014 Author Share Posted February 27, 2014 Yeh I know I'd need down pipe too thanks Yeh 2.5 inch. Think I'm going to start with centre first then maybe do full see how it goes Quote Link to comment Share on other sites More sharing options...

Gambit Posted February 27, 2014 Share Posted February 27, 2014 It's definitely Decat pipe and anything can be made to fit. Just cheaper if it's a straight fit :) Quote Link to comment Share on other sites More sharing options...
BoozyDave Posted February 27, 2014 Share Posted February 27, 2014 I've fitted decat uppipe, 3" decat turbo back exhaust, with a small res box and rear box, it's not that loud, just releases the proper boxer sound to it's full potential :D 2 Quote Link to comment Share on other sites More sharing options...

stants Posted March 2, 2014 Share Posted March 2, 2014 Just gone for sports cat and twin resonated centre section.3" all the way through, Sounds nice not overly loud no drone just a little burble at idle. (And i can her the turbo spooling up now) :-) I wasn't looking for major prefomance gains or something to wake the world up. I just didn't want to pay dealer prices to replace a dead exhaust. So far seems to be running well can t see any gains as to power (i wasnt expecting to be fair) Boost is falling withing the same ranges so no spiking or overspool. Only thing i'm not happy with is the 'all inc price' didn't include a new tubo gasket so i'll have to change that soon Quote Link to comment Share on other sites More sharing options...
hilli182 Posted March 3, 2014 Author Share Posted March 3, 2014 so I got out bid on yet another mid decat pipe last night, that's three now so I went back on eBay this morn, and come across a 2.5 inch decat down pipe rather than the mid pipes I've previously been looking at, which was listed 10 min from my house :) picking it up tonight so will try and fit later in the week Quote Link to comment Share on other sites More sharing options...
BlackBosh Posted March 3, 2014 Share Posted March 3, 2014 You won't be disappointed. Oh and the smell, I'm jealous of cars that get to smell me as I pull away lol Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
hilli182 Posted March 3, 2014 Author Share Posted March 3, 2014 I haven't had chance to get under and have a look at standard set up yet. The pipe I'm getting looks quite long (ill put a pic up later) Will it remove the first cat or both? Apologies for the daft questions by the way ha Quote Link to comment Share on other sites More sharing options...
