Hi-Flow Cat or Resonated Midpipe?
I have just discovered that my Hi-Flow Cat is toast so i had to put the stocker back on to pass emissions today. Well I either have to buy another Hi-Flow or a Resonated Midpipe and change back to stock every year for inspection. My question is the performance enough difference to do this every year and get the Midpipe. And also i would have to leave the airpump on all the time would this effect it pumping air to nowear?
thanx

I don't know why you think that you will have to switch back to the stock cat to pass emissions. I have a Bonez cat and I passed emissions here in Charlotte, NC with flying colors. I haven't had any tuning on my PFC or anything and I hardly even registered on the scale. I can post my results when I get home if you want. I did run the car hard for about 10 min before the testing to get the cat hot but that is all I had to do.
I guess what I am saying is that I would go for the hi flow for sound, smell and emissions reasons.

What brand high-flow cat do/did you have? What happened to the cat?
I too have heard good things about the Bonez cats.
Personally, I'd go with a high-flow. Less stink, less boost creep problems, less noise. Just depends on how hard-core you want to go .

Im not saying switch from Hi-Flow back to stock to pass, I passed fine on the Hi-Flow I have till this time. I took it off to replace it with the stock one and the ellement came out in pieces. Its bout 3 or 4 years old and ive put bout 40k miles on it but I bought it used and dont know the previous millage. I also dont know the brand but think its a N-Tech, at least thats what it looks like. So you guys think i should just stay with a Hi-Flow then?

I've heard of people having trouble with the N-tech. Yeah, I'd get another high-flow and be done with it.

Laters!
