Default Ordered Some High Flow Cats

I went with Magnaflow #59956 which was recommended from a member here in an old thread I found. Got them both for $140 shipped on a Cyber Monday sale. I guess Random Technologies had the best ones a while back, but I believe either they closed or Magnaflow bought them out. I read different stories on this. When I had my C5 at the tuner, he told me my cats were very restricted and I would be better off going catless or get high flow cats, so hf cats it is! Anyone run these or other high flow cats? How do you like them?

I went with Magnaflow metal core universal cats but 3" in and out after the 3" header collectors. All good 4 years later.

Good to hear since I will be keeping them for a while. Although I went 2.5" on both ends since everything under the car is 2.5. I was debating on the size, but when I had my pup cats removed the stock main cats were 2.5 and my exhaust guy welded a pipe and flanges there. These will be welded in though.
