Default Magnaflow Cat - any problems?

Hey all... been a while since I've posted here. Summer is around the corner, and it's time to get the car back on the road...

Question: Anyone here running a Magnaflow Hi-flo cat? If so, any problems with e-tests? I know it's not Cali-legal, no problem, I'm in Ontario, Canada. I'm looking to buy a cat this week, found a good deal on the Magnaflow's on Ebay, and just don't want to get caught at the sniffer.

'94 LT1
Pacesetter Shorties
3" Flowmaster cat-back
stock motor

Here's the link to the Cat if anyone else is in the market for one... Price ssems pretty solid!

Same here, the exhaust note increased ever so slighlty so I would say they flow well and my emissions are as low as they have ever been, and that's with over 160K on the clock.
The tag is in the car or I would give you my numbers, trust me you will not have a problem passing. You shouldn't even need any tips but, put some miles on a new cat before you get it inspected (about 100 I believe) and have it inspected when the car is up to temp.

My cat's been doing its thing for 20K miles now. Passed CA emissions no problem with a 185K mile engine.

Good to know if I ever need cats. I love CA, but at the same time I hate CA.

Same way I feel about Oregon. Going Green and letting "Gheys" that touch under aged boys wieners into office seems to be the "IN" thing here.

Just took a look at your link.
The one I used on my 93 T/A was Magnaflow 93441. It has 3" in and a 3" male ball welded flange that mated right up to my Borla catback.
