header question!!!
 

ok so i bought my header bout 2 months ago. and its the dual outlet header for the 6 ports. i saw on mazdatrix site that they have a Y flange can i weld that on the header to make it a single outlet. so i can just weld it on to the y-pipe instead of gettin an H pipe done or welding 1 outlet to each muffler?

Yep.... Probably need an extension pipe to bridge between the Y-pipe and the end of the collector.
