think my cat just blow up and is now blocking exhaust
after a hard 3rd gear pull up a hill i notice something wasn't right. car seemed very laggy like no boost, looked down at the gauge and it only showed about 3-4psi. got out of the when i got home and could hear a rattleing from about the middle of the car where the DP meets the stock midpipe. drove it a little more and had a huge boostspike 18-19psi!! then the clutch started to slip!! when i had the boostspike the car spooled up faster then ever before. help thanks

Sounds more like a wastegate issue... If your cat blew then it's probably in small pieces that wouldn't block the pipe. Also, I would believe increased back pressure from a blocked exhaust would keep the turbo from spooling all the way, not overboosting.
