Re: LS Swap Exhaust Question

On my previous LS swap (into a 66 Chevy II) I deleted the cats. Now I'd wish I hadn't. The exhaust smell can get pretty bad at times and I may consider putting some on now. The plus to leaving the cats on is also that they quiet the exhaust enough that you can often get away with running no muffler. I'm currently doing an LS swap into my C10 and will be using the Y pipe and cats from the donor vehicle
