I have a 98 k2500 the exhaust is pretty such screwed. I’d like to just put a whole new system on it but I’m not really sure what I need to do im pretty sure my truck need two cats but I also don’t know if it’s worth it considering the age and Mileage of the vehicle. The truck is very loud should I just straight pipe it and put a few mufflers on it. The current exhaust only has two cherry bombs and one of them isn’t hooked. Any tips would be helpful.
