Today i was driving my 2011 wrx sedan, i was driving hard and everything was okay and all of a sudden after i turned a corner i lose all boost and for some reason there is little to no noise coming out of my exhaust. No exhaust pressure. My COBB boost controller is reading around 2-3 psi at around 4000rpm.
My mods: Cobb Air intake with a stage 1 tune (91 octane) Invidia Q300 Catback
Also: A bracket broke on one of my cats causing it to rattle, i didnt fix it could've broke on the inside?????
Tried Re-Mapping, didn't work, No check engine.
Right before 100k KMS so I'm still covered under warranty
ANY IDEAS WHATSOEVER AS TO WHAT THIS COULD BE ???
