Dual exhaust issues

[foxtrot]

I don't really like headers, I've had them in the past and had to replace the gaskets once a year... Also, I'm not racing this car just driving it.

Yah I have 5/16' flange headers, go threw gaskets alot. The Sanderson have thick 3/8" flanges and seal with RTV, no gaskets. I even used the red RTV on the collectors. I also saved 10 pounds over manifolds.
