I'm wanting to add cats to my Dinan xpipe to cut back on the rich exhaust fumes. That's my only complaint with being catless. What would be the best options for doing that?
There's a guy on here selling the stock secondary cats, would that work just welding them in to the same location?
Or do high flow cats in the primary or secondary?

I know alot will say to sell mine and buy a different xpipe but I don't think I want to go that route. New high flow catted xpipes are pricey.
