Hey guys,
Wondering if i could pick you brains. I bought my car with an offroad y-pipe on it (no cats) and this year i'm going to have to get emissions test done. My question is, should i add high flow cats to the offroad y-pipe, or just take the off road y-pipe off and put the stock y-pipe on that has the cats already on it, as i have the original that i got when i bought the car. The rest of my exhaust downstream of the y-pipe is aftermarket. I also hate the stink of no cats.

I'm just wondering if i should take this opportunity to put the high flows on as i wanted to do that anyways at some point.

Thoughts?

 

The stock Y didn't have cats in it. The stock cats are in the header pipe right off the exhaust manifolds.

 

Ok,
well i have the original pipes that have the cats on them that bolt on. for simplicity i won't call it a y-pipe.
