My 9000 cse 2.3t last week spit what looked like a fiberglass wig out of the tailpipe. i pulled on it and it kept coming. this has happened 2 times. the third time, i lost my boost going down the highway so i floored it. POW! a huge cloud of that fiberglass stuff came out and the car resumed operating as normal except for 1 thing. now when i step on it, i hear the turbo spool and also a loud chhhhhhhhhhhh. it never sounded like that before. did that block in the exhaust hurt my turbo?
