hi when i installed my turbo setup i lost the 2 gaskets that go from manifold to wastegate and from wastegate to screamer pipe think the garage that installed it used some instant gasket on these joins

when driving car n i hit boost the screamer pipe dont scream ! lol it sounds like my exhasut is leaking.

i have ordered the right gaskets for the screamer pipe n wastegate just wana now if that is my problem??

thanks
