Default Louder Now

Hey guys i bought the alumanized magnaflow axle back set w/ lt1 tips for my 93 and it's not loud enough even though its basically a set of glass packs. i was thinking about doing some excavation on the cats hopefully to avoid spending money and ultimately get louder any word on o2 sensors or issues with modifying the cats would be appreciated

I removed the cats, the center muffler and both rear mufflers and installed a magnaflow muffler that has 2 inlets and 2 outlets with a cross over (X pipe) built into the muffler. I installed it where the center muffler was. It has a great sound that isn't too loud. If you remove the cats you need to reprogram your computer to make it run correctly again.
