Im on my second attempt at fixing a damn exhaust leak between my HF manifold and adapter plate... Ive been using OEM honda HF gaskets but still get leakage. This time im going to try using a metal based make-a-gasket type material and some mega copper... i was wondering if anyone else had been having exhaust leak problems and how they fixed it. Thanks

 

i use the metal hf gasket and the metal dsm gasket on the other side, works perfect.

make sure you're using grade 8 or above hardware, i use grade 12 bolts for the turbo side and stainless for the manifold side. no problems

 

Something is warped or not tight enough or??

 

put some high temp sili on it or get the thing surfaced.

 

high temp siili will melt. inless they have some that can withstand temps higher than 650.
