I want to get a Mac pro chamber for my long tune headers. I know that they don't sell it with cats and in illinois you need cats to pass emissions. I was wondering if there is enough room to fit some of the mini Flowmaster cats on the pro chamber? If anyone knows anything that might help it would be greatly appreciated!

Theres always room. I dont have this problem cuz socal=no smog check. U only have to smog it when u first buy it then never again but there should be more then enough room to puts some cats in
