Hey guys, so I have a '91 MK3 just finished installing a 3" exhaust from the DP back. After the exhaust I tore into the engine a bit to replace my wastegate actuator. Put everything back together and it start and runs great (sounds pretty decent too!) however my turbo seems a lot more sluggish when spooling and as soon as I start to make boost I get a grinding noise. I was thinking maybe a gasket on the downpipe or something but I really don't know where to begin to look. If it helps I also have a pretty big exhaust leak somewhere and the grinding is metal on metal.
