Hi everyone,
I have a '99 Suburban that I got for free in non-running condition. Fixed all of the mechanical issues and cosmetic issues, and part of that involved getting new catalytic converters. I went with a Walker cat that seemed decent. Anyway, about 6 months later, one of the cats is rattling inside (not heat shield), and truck sounds like a POS. Runs fine otherwise, I just can't stand the rattle. So I need to replace the cats again. Annoying, but is what it is. My question is, is there is significant performance benefit (or longevity benefit) to going with the Magnaflow high flow cats? It's about double the price, but I will go for it if you guys tell me it's worth it. My only experience with high flow cats is my 400 HP Civic Type R with a full 3 inch turbo-back exhaust and high flow cats, and it is so loud inside when accelerating that I would actually not be happy if it was my daily driver. Those of you that are running it, anything annoying about it? Noise, vibration, etc? This is my daily driver, and sometimes for the family when we need something larger and I don't feel like putting miles on my other cars. Thanks for your advice.
