Hey everybody,
just as the title says I am looking to replace my cats on my 05 suburban. I was looking to see if anyone has good recommendations for what cats to go with that aren't garbage?
I think I have to replace my injectors as well, I think that may be what caused the cats to go bad in the first place. Any recommendations for injectors as well?
I have an 05 Suburban as I mentioned above, LT trim with the Z VIN. I have had issues with a misfire since I bought it a few months ago, thinking the misfire was just plugs I changed the plugs, coils, and wires and still had the misfire. I've tested the compression as well, the numbers came back good. Cleaned the throttle body and MAF sensor. This is the last thing I can think of because my acceleration is horrible, the car is very sluggish, I have the cat rattling noise that has gotten worse, and I can smell sulfur occasionally. I had a friend of mine hook up his OBD scanner it showed the misfire on 3 and slightly on 1. The misfire does go away while driving.

Eventually, I would like to put a magnaflow on this vehicle or anything similar to get that deeper sound, recommendations here are welcome as well.

Thanks.
