was going to get these

now I'm not sure.

How does the magnaflow Y pipe flow compared to stock?

Should I just get new cats welded into the factory Y?

What kind If I go for universal cats? Standard or spun cats? Ceramic or metallic? Magnaflow or Thunderbolt?

What size universal cats would I need? Not sure the size of stock piping. Hard to crawl around under it with broken collar bone.

so many choices. Truck is all stock at the moment

 

I'm on the same boat, i was thinking of getting magnaflow high flow cats welded in the place of my stock cats lol

 

Might throw a code with the high flows.

 

Do they do an actual sniffer test where you live, or just an OBDII plug in for inspection? If it's just the latter, I'd save the dough on the kitties, hollow them bishes out, and spend about $250 on a custom tune and get the kitty codes turned off

BTW, it is my understanding that the Magnaflow y-pipe flows better than stock

 

No visual or sniffer, but I'd rather keep it legal for when I do decide to sell it.

 

Ideally I should just get a set of ebay longtubes to fix it. But as long as I'm living with my parents I can't mod the truck. That will change in a few months, but I need the truck in the mean time and I need to get a better job first

 

Well Just ordered the magnaflow Y pipe. Got a good deal on y pipe ($367 w/ free shipping) and 2 Denso upstream o2 sensors for $37 each

 

Good deal man

 

Not bad at all. The stock Y-pipe on our trucks isn't all that great. That magnaflow should be MUCH better.

 

$70 for old kitties at scrap yard
