I was running a cat back straight pipe for a bit, that sounded awesome.....sometimes Sent from my HTC One M9 using Tapatalk

I had that in my hand the other day, job for one evening this week Sent from my HTC One M9 using Tapatalk

That's on my to-do list to, mine are terrible atm Sent from my HTC One M9 using Tapatalk

The last one in my downpipe but only when I can sort a map for it Sent from my HTC One M9 using Tapatalk

Sod the neighbors, Impreza's are meant to be loud and abuse the ear drums, imagine how mine feel at 6am lol and I have a decat waiting as soon as I can get a map on it Sent from my HTC One M9 using Tapatalk

Or buy a blitz lol Sent from my HTC One M9 using Tapatalk

I think it's removing all the Cats is where the problems start, other option of course(to play it safe) would be full decat an map, then you know it's right regardless Sent from my HTC One M9 using Tapatalk

I'd would of thought you would be fine,@Tidgy would probably know better tho Sent from my HTC One M9 using Tapatalk

Ur an STi, you only have two, buy a non res centre pipe and you will be fine Sent from my HTC One M9 using Tapatalk

Me personally, I'd do as prodrive did and leave the one in DP and bin the rest. If I remember right, wrx has 3 cats, STi 2 and prodrive 1 Sent from my HTC One M9 using Tapatalk

What are you using to code read? Sent from my HTC One M9 using Tapatalk

I believe that's triggered if the pre and post cat O2 sensors reading are similar(cat appears to not be doing it's job) Sent from my HTC One M9 using Tapatalk
