timmyjk7 Posted September 24, 2015 Author Share Posted September 24, 2015 Thanks guys... As I am no mechanic I am going to let TGM who are a motorsport specialists have a look Monday. I am hoping its either a clogged cat or a faulty boost solenoid. I will let you know the outcome .... good or bad! Quote Link to comment Share on other sites More sharing options...

Tidgy Posted September 25, 2015 Share Posted September 25, 2015 How much experience do they have with subarus? Quote Link to comment Share on other sites More sharing options...
timmyjk7 Posted September 28, 2015 Author Share Posted September 28, 2015 How much experience do they have with subarus? even though they are mainly a Honda specialist they build and run their own race cars and have done several front cover Impreza's. They also work closely with Surrey Rolling Road who have a specialist so i am confident of their abilities to resolve. On a separate note the car passed emissions at the weekend so that clears the CAT, next is MAF Quote Link to comment Share on other sites More sharing options...
timmyjk7 Posted September 29, 2015 Author Share Posted September 29, 2015 So it appears the issues ARE with the CATS. I am just trying to rally around to get the two decat pipes before Thursday so they can be fitted in time for racedynamix to tune on Friday Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 29, 2015 Share Posted September 29, 2015 Do you know how the cats have failed? Weird how they pass emmisions but are actually fubard. Quote Link to comment Share on other sites More sharing options...
GMInsite Posted September 29, 2015 Share Posted September 29, 2015 Where is the primary cat? I have a decat downpipe from the turbo and i guess the other is in the up pipe? Quote Link to comment Share on other sites More sharing options...

Scoobyghost Posted September 29, 2015 Share Posted September 29, 2015 How did you pass emmisions with a decat? [emoji15] Quote Link to comment Share on other sites More sharing options...
GMInsite Posted September 29, 2015 Share Posted September 29, 2015 So where is the cats on the wrx? one on the downpipe and other in the mid pipe? Quote Link to comment Share on other sites More sharing options...
stants Posted September 29, 2015 Share Posted September 29, 2015 Prob same way as you did ghost [emoji38] 1 Quote Link to comment Share on other sites More sharing options...
Xander Posted September 29, 2015 Share Posted September 29, 2015 Think it's only one in the downpipe total on wrx might be 2 both in the same place.

[emoji9] [emoji9] If you don't have one on uppipe the only cat will be in the down pipe. If that's decat then you would fail an emissions test.

Scoobyghost Posted September 29, 2015 Share Posted September 29, 2015 Ah, I keep forgetting about that. I had a quick look and it seems you have two cats post turbo. One in downpipe and one directly after that. Quote Link to comment Share on other sites More sharing options...
GMInsite Posted September 29, 2015 Share Posted September 29, 2015 Im fully decatted then :) I have no clue why mine seems sluggish then, its got a uprated fuel pump / full exhaust / intake / uprated intercooler etc Quote Link to comment Share on other sites More sharing options...
kershaw-330s Posted September 29, 2015 Share Posted September 29, 2015 The sti only has one in down pipe Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
timmyjk7 Posted September 29, 2015 Author Share Posted September 29, 2015 But the STI has a catted uppipe surely? Quote Link to comment Share on other sites More sharing options...

Xander Posted September 29, 2015 Share Posted September 29, 2015 Think they stopped the catted up pipes after the cats fell apart and got sucked into the turbo. -- I make Films for businesses and people. I also make websites. Quote Link to comment Share on other sites More sharing options...
timmyjk7 Posted September 29, 2015 Author Share Posted September 29, 2015 I have learnt something new today :) Quote Link to comment Share on other sites More sharing options...
timmyjk7 Posted October 1, 2015 Author Share Posted October 1, 2015 So decats have been installed and power seems to have improved from 2-3.5k rpm but then dies which we think is down to it now needing a remap. The dash then went like a Christmas tree with all the lights including the MAP and Boost sensor error message but the garage reset this and they haven't come back on. i am hoping the decats have corrected the boost issue and with the remap it will go back to how it is was. The final final issue is now the stupid noise this car makes.... i sound like a wannabe rally driver. Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted October 1, 2015 Share Posted October 1, 2015 The lights will come up because your decat will be allowing higher uncontrolled boost. The sensor expects some back pressure and there isn't any now. Quote Link to comment Share on other sites More sharing options...
