if used cats with true duals will i be slower in 1/4 et?

[SLOWBRAEATER]

I dont really wanna use cat converters but if i got hi flow ones from summit or somewhere do any of you think my 1/4 et or mph would be worse if i had cats on instead of no cats?, or will i get a better time without cats?

my setup goes like this

pipe to x pipe to more pipe to bullets to turndowns.

where is the correct place to put cats on a true dual setup?

If i run the one o2 simm can i still use the two cat converters or will the pcm set a code or make the car run crappier since it cat read the cats?? thanks

do you have true duals right now? i would think thats ballsy for a V6. but anyhow, cats on a true dual setup is defeating the purpose...isnt it?

[SLOWBRAEATER]

yes i do have true duals right now, i wasnt sure if my et would be worse if i ran cats instead of running no cats, i just figured the sound may sound a little better with hi flow cats

The legal place to put them is before the crossover.

I will be having my true dual installed within a month.

so basically have my setup like this if i run cats.

headers to pipeing to cats to more pipeing to x pipe to pipeing to bullets to turndowns? are you gonna use cats dom? and in your opinion do you thinjk the 1/4 et would be better with cats or without cats?

Ok, we definately need sound clips of this. I'm very curious to hear it.
