I wanted to get a high flow cat to complete me tbe so I can use the base maps tune for it. I didn't want to go the test pipe route because I need it to pass PA inspection. I found this but I was a little scriptural because of the low price of it compared to other high flow cats. It seemed more like a test pipe. Can anyone confirm that it will pass inspection. http://www.importimageracing.com/tur...EaAjf9EALw_wcB

 

That clearly looks aftermarket.
In california its a visual inspection and it would fail.

Why dont you take your stock cat and knock out the catalyst material?

 

It won't pass the visual unless you cut off your oem cat heat shielding and tack weld it on both sides of the catalytic portion. You will also want to look for a non-polished finished hfc. You want it to oxidize over time so that it blends in to the rest of the undercarriage and looks like ****. That's what the state refs and smog visual inspectors look for. They like rusted **** parts. This has been my experience.

 

so would it make a difference if I went with the more expensive AMS or Cobb tuning ones. They seem to look basically the same. I'd prefer to keep it as legitate as possible so if I had to buy one of the more pricey ones that's fine. I'm just looking for the cheapest way without having to make shift things.

 

I can tell you it's a 200 cell HFC, and that's a really low price. Here's the link to the same product on the Manufacturer's website, but the price is higher(although they might price-match if you called them).

I have a HFC that I passed Cali smog with flying colors, Look pretty inconspicuous if you ask me, let me know I may sell it

 

I'm pretty sure PA emissions testing varies by county or region, so you'll have to check for your area. This might help (though I'm not sure if it is outdated): http://www.drivecleanpa.state.pa.us/...q_customer.pdf

I've never had issues running a high flow cat with my other car but I think they only do OBD-II and gas cap tests around here. I think they do visual inspection on all cars in some areas, and only on older cars in others.

 

Re the gutting out stock cat - what's people's experience with this, do I need to get a second 02 sensor spacer or am I better off to disable it in tactrix (I noticed a disable second 02 setting in there)

 

If you gut the cat you will either need to space out the o2 sensor or as you said using openecu. However it's not just a one click type of thing. There are some pretty good how to out there, but you will need to have a rom established to be able to do this type of stuff. The GST base maps have these options setup so you can work with them.
