Im making my own exhaust, im taking the facotry y-pipe, cutting it where it joins, and making it a true duel, should be a lot better then stock.

But, to make it legal, i need a cat.

If i use the cat as the H-pipe, would it be legal because it is on the exhaust?

I know it wont do anything, barely even equalize pressure, but would it pass visual because its on there>?

 

Actually, if its dual exhaust you are after, you'll need two cats... one on each pipe. Might be a good idea to check out the factory dual-cat setup.

Cat won't do **** if you use it as an H-pipe... and its gotta be in the factory location anyway. Since you need two cats, thats why I suggest you look at the factory dual cat setup.

 

Someone sells a dual in dual out cat. Not sure where I saw it ?

 

In alot of places true duals aren't legal because of the cat position change. Check your local smog laws.

 

Think I saw them in JC Whitney catalog.

 

i think its legal in NY long as you can pass visual w/ the cat.
