At full boost it seems like there is a lot of exhaust noise coming from the exhaust side of the turbo. I checked to see if all the bolts were tight on the 5 bolt flange and they were.....but it looks like there is no gasket in between the turbo and the downpipe flange...is there suppose to be? Or is it suppose to be metal to metal.

 

Theres suppose to be a gasket in between.

 

thanks...makes sense...sry for such a dumb question
