Who's Running High Flow Cats? I believe one of my two have blown out and looking to see who's running High Flow Cats on their car and what are the gains or power losses you've had. Does anyone have dyno sheets to prove gains with the different brands out there?

i asked the same question on here and got the frozen boost responses. It is an interesting concept. however, i can't stand the stink of no cats, especially on me after I'm done driving the car, so I went with the LG 3" cats which are slip on and didn't need welding. Also, metallic substrate. They are 150/each for the 3" version and 200 for the 2 1/2" versions. I'm planning install this weekend...

I have the single cat on my 93 and replaced it with a "High Flow" Magnaflow and am very happy. I believe it flows better than stock. Exhaust note from cat back got a little louder!
I have seen others recommend it as well. Passed Emmisions easily. Not sure about metal substrate.

just get it tuned out, itll cost you less then buying them 
I had magnaflow with ORY then had to throw in a magnaflow high flow cat and it actually helped me out a little down low with the added backpressure but now my car is whisper quiet compared to what it was and I hate it
