Default High Flow Cats - which ones?

Random Tech's are ridiculously expensive, so I'm really not trying to go that route. What other cats are out there that won't restrict my 408 too much and won't kill the wallet? I've seen that magnaflows are pretty cheap but haven't heard anything about their flow. I have also looked into the option of dual cutouts but right now I just want some feedback on flow/price comparisons between the high flow cats on the market.

I second the dynomax powercats ,metalic substraight flows very well and is durable.
Also the cats are very compact at 4" dia and 11 1/2" long.

z-ya - You mean you second the dynatech's?

TheBlur - Do you mean they are the same thing or that they are comparable in price/flow? Either way, what's your stance on it?

@ 590 cfm the RTs outflow all other "hi-flow" cats by a big margin. For a few extra bucks it's going to be worth it on that 408. These cheaper cats are going to be restrictive.

Years ago that info was posted; maybe by Patrick G. Not sure if it is still around.

My recollection is the car sounds flowed well but burned up easier.

I'm also looking into cats and have mostly been recommended the random techs.

Sound, flow, and clearance are all important to me, and if I have to pay a little extra to do it right the first time I will.
