exhaust manifold issue

[H2ONUT]

I have the GLM's. Perfect fit, and no problems...

Bought them on E-Bay from a guy in Jersey. $450 for everything. Installed myself.

I noticed GLM's after I bought mine. I did more research after the fact. I went with protech's only because of the ceramic & EDP coatings. I guess now a days there all good. GLM's were around 700 for my engine. I could have saved 200.00 but again not sure how they coat theres. I know there not ceramic coated though.
