Do you have an exhaust leak between the turbo housing and the downpipe?
This gasket will seal the turbo housing to downpipe.
Some downpipes leak under the puck area.
Made from .065 thick graphite impregnated high temp material with stainless steel core.
Can be used with the stock GM elbow, ATR, Meese or a Terry Houston downpipe.
Will not interfere with either the stock puck or pucks up to 1.250".
