Prolly a dumb question, but all of you who have the off road Y-pipe (this replaces the cat right?) would not pass emissions? As I stated in my other post, I want to do long tubes and the corsa system but I need to pass emissions. What do I do with everything in between to do so?

After reading alittle, I found that true duals with the corsa system would have to be fabed so it looks like that is out.

 

What year is your car? If you have to pass tailpipe emissions, there is no way you will pass with an off-road y-pipe.
