Are Hi Flow cats legal?
I live in PA and starting January 1st we will be required to pass emissions testing. I was thinking of putting on some test pipes, but obvisouly I can't do that. My next option was putting on some hi flow cats... Are these LEGAL? Even if I find a set that are CARB certified, I found the following link posted by the EPZ about converters...
Please read, (at least the top of page 4) and let me know what you think... Thank you all..

Yes and No...
Technically we you can not change the Cats below 50,000 miles. UNLESS there is damage, Like by running rich or using bad fuel your Original cat element broke apart and needed to be replaced. Or you could have hit a rock.
Now, the RANDOM TECHNOLOGY High Flow Cats $500.00 are CARB Certified. But the above applies...
I hit a rock
Seriously I did.

Ohio is yes and no too.
Technically they are legal if you can pass emissions (only some counties require this). However it is illegal to change the cat before 5 years or 50,000 miles unless it has been damaged or is no longer working. So, if you go into a shop with 5000 miles on your car and hand them high-flows, they will likely say no. However, this depends on the shop. You can always put them on yourself, but that would technically be illegal too.
Don't worry about it. If you don't pass emissions, you get a second chance. When you are required to go, go early. This will leave you plently of time to swap back to stock before your registration expires.

Look at the braded flex point on the OEM exhaust in this pic, Nailed a rock on the freeway going 85 on the way to vegas in the middle of the night.. I know that isnt that cat, but, Ociffer, The shock from the rock shattered the catalyst and cracked the header!
