not too sure but since you havent gotten any replies yet, might as well put in my .02

1. believe so

2. yes(and almost as free flowing)

1. it depends, there is a lot of debate about it. You will need an air pump to pass emissions and the cat will last longer with the air pump.

2. Yes, a hi-flow cat is noticeably quieter than a midpipe. It is about the same noise level as a resonated midpipe (rx7store style).

Rynberg..

When you say last longer?? how long is that?? a year or two??
im running a single turbo, and Not sure if Airpump will even go back on.

I am currently running a midpipe. And im starting to get tired of how
******* loud it is. I guess im getting old, I don't want me and my car
to sound so obnoxious.

anyone with 400-500rwhp using a high flow cat??

thanks again..

not really, ive never seen a high HP single turbo car running a hiflo cat, by then you'd move to a straight pipe, and didn't you just crash your car slingshot?

get a resonated mp

The rx7store resonated midpipe has a Magnaflow muffler in it. It has a bit different tonality but is as quiet as my hi-flow cat was.
