What's up. I got a 04 Tahoe with the 5.3. I was getting cat codes an loss of power so I couldn't afford to get new cats at the moment so went to a shop had them chopped off. I have a flow master 40 an Its always sounded good. My buddy is gonna tune my rear 02s out so anyway had the cats cut off today and I CANNOT stand the sound it makes now. Sounds raspy an I hate it. is there something i can have welded back in instead of cats like resonator or something or do i just need to order some cats
