I have all stock exhaust except for an electric cut out before the muffler.....i want to put hi flow cats in there but was wondering if i will only need two instead of the four already in there. any ideas?

I am building a system with cats from Random Technology. They claim that they flow the best on the market. 582 CFM per cat.

2 is fine. The first 2 are only pre cats for warm up

do they just run straight pipes through the pre cats or leave them on?

 

how much are you paying for those random techs, which model are u using, where are you getting them from? i plan do do something similar.

 

I am calling them on Monday to talk to them directly. Their cats have the best finish and flow rate which I have encountered and unlike Bassani, they meet emissions. There have been alot of issues with Magnaflow cats lately.

TB Check with me on Monday PM

 

JimJr,
What other mods do you have? If you are fairly stock, you are going to KILL your low end torque...

 

Not if you use the proper crossover.

These guys are the best.

basically stock right now.......ordering a 5lb predator and filter the first week of february so i figured i'd be ok installing these after i get all the stuff on. what do you think? will the hp gains be enough to accomadate the loss of low end torque? it should gain some top end right??

 

Why not put cut outs on each side befoe the stock cats. That would be the best of both worlds.

 

i have one on there right now but the retard that installed it...installed it after the cat. already ordered the cats........think i could sell them and just fix the cut outs?

 

I'd say if you already have the cats do what you have planned. It would probably be cheaper. Either way it probably doesn't make a huge difference.

 

sounds good...........just dont want to kill the low end torque like someone said i would.

 

If its lightning exhaust your are talking about unless you are running over five[5] hundred horsepower then why change they are a certain amount of back pressure that should remain. like my friend said sound does not make horsepower but you sure can lose some if your not careful high flow mufflers will lose you some horsepower but if its sound you want then go for it/
