5 years ago i bought a direct replacement exhaust manifold for the drivers side thinking even though it was not cracked, I would be safer buying a new stock direct replcement, since thats the side that seems to crack more frequently.It is a new replacement for the stock manifold drivers side.They don't make a manifold for the p***enger side.I started my car up the other day and heard a ticking noise on the p***enger side.I think it is the p***enger side manifold.Should i take the manifold off and get it ceramic coated at 2000 degrees(would it be worth it?) or just simply welded up at this place that welds 87GN manifolds.
