It depends on how much air you are pushing through them; check out the Random Tech site, maybe they have some flow numbers.

You can pick up Carsound (made by magnaflow) universal cats for 40 or 50 bucks. They flow as well if not better than the Random Tech, from all the sources I've seen.

From what I've heard, Carsounds do *not* flow as well as RTs. I haven't seen any numbers to back it up, but I heard it from an in-house dyno shop who seemed to know their stuff.

The Carsounds do flow better than the regular RTs. I have some results someone did and posted on ls1.com. I'll see if I can find it...

Last I read, they're all quite close.

I recall the 3" Carsounds flowing a bit better than the base RTs, but not as well as the $$$ RTs.

Basically, it comes down to how much are you willing to pay for a little better flow?

There was an old post on here, that referenced several comparison tests with disagreeing results... but I can't seem to find it.
