Is there anywhere else I can get a copper exhaust manifold gasket besides TTI racing?

Use a stock(mitsu) multi layer exhaust manifold gasket. They are much better at sealing and hold up great. The copper one I had from TTI was made fine, but it always leaked and was difficult to seal. This was not the gaskets fault, but any imperfection in the manifold itself and it will leak.
