Catalytic Converters
I have LS1 Edit so the O2 isn't a problem. However I'll need to get two 3" Catalytic Converters welded into the Y-pipe to pass the emissions.
Does anyone know of any cheap places to get these? Doesn't matter if it's hi-flo or not as I plan to gut them.
Or any suggestions?
I had also thought about the Mac setup since it comes with cat's but I have heard that regardless of the cats, that setup sucks for midrange power.
Thanks
