Hi all, i have a set of Trd Copy extractors, the ones that option 1, streeter, and kaizen sell i assume most peeps know what they roughly look like.

Basically the bolts at the bottom of the extractors to the exhaust keep coming undone. Im trying to think of ways to prevent this, or to fix the reason for it doing it.

Basically i have a gasket between it, gasket glued, the exhaust uses two bolts with nuts clamping it tight and high tensile spring washers on the bolts. I have done these as tight as possible numerous times, and have even loctited them and its still comes loose

Could this be there is too much exhaust pressure hitting that part of the exhaust? otherwise all i can figured is the combination of the heat and engine movement.

I have heard of exhaust silicone stuff or something that apparent is used in this situation and it just doesnt come loose from the heat, anyone know where to get this and how good it is?
Also i have thought about using several nuts on the bolts to keep it clamped out tight

Other than that im out of ideas and im pretty sure its just gona keep happening unless i do something definate

Any info anyone can give is much appreciated

Cheers

Grant
