I'm trying to figure out what I need to do with the cats and pre-cats, yes, a little confused to how many there are. I read some on the warpspeed y-pipe. Now, if I was to go with that option, how many precats will I be eliminating? And how many would I still need to replace after the y pipe install? I see Walker is a trusted source, I suppose I will have the others replaced instead of gutted. Don't have the patience for a rusted exhaust, especially with no work space under the car. Yes, exhaust shop it will go.

 

You have 2 pore cats (1 for each bank, # 12 and #20020) and 1 main cat (after the y-pipe merge).

 

Could also be fed spec since it's a 2000 ..

If it is than , both precats are integrated to the y pipe,and a y pipe eliminatest both,and the main cat can be replaced with a test pipe of hf cat,

 

You don't have to do anything b/c it's a 3.0. They're not dangerous. Worst case is if they get clogged at high mileage.

I would Y pipe it if it's a fed spec like nester said. It never hurts to pick up some extra power

 

i didn't feel much with my y-pipe.... but i also am chocking it with stock b-pipe and muffler

 

Ahh, maybe peeps should know that I'm slow and can't read and post DEK or V35.
