.Catalyst. Posted February 18, 2013 Share Posted February 18, 2013 If you have a catless UP there should be no bung. The EGT bung was in the catted UP to monitor the catalytic converters effectiveness. My spec.B [#163] Project Thread with Pictures Get CryoTuned!

car_cursed Posted February 18, 2013 Share Posted February 18, 2013 Some (TurboXS for example) still have the bung I believe, just go to a hardware store buy a few bolts and see what fits. or contact the manufacturer. Link to comment Share on other sites More sharing options...

Max Capacity Posted February 19, 2013 Share Posted February 19, 2013 Take the pipe to the store and match up the threads. Cut the bolt so it doesn't stick into the flow. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
