I've down some searching and even listened to a few video clips but I'm not convinced I've found the same sound.
It sounds just like there is a plastic bag, or a piece of paper in my exhaust.
It is only really noticeable at low revs, or when I blip the throttle; and it's not that loud. I'm pretty sure it's coming from the center of the car (underneath), not the muffler or turbo. So I'm thinking downpipe cat. Is this an exhaust leak?
About 10 days ago it was raining really hard and I threw an exhaust temp CEL (P1312). However I'm confused because:
1) I've thrown a CEL when it's raining before, and
2) I have a AP stage 2 re-flash.
Mods include: Cat-less UP(without bung), TurboXS turbo-back w/ cat, Cobb stage 2 re-flash.
2002 WRX, ~80,000 miles.
Any help, would be great.
