Reusing OEM cats on catless x pipe + Longtubes
So just throwing this out there cause someone must have done it by now...
You got a set of ********** long tube headers and that company's catless x pipe for a really great price. You wanted the catted Xpipe but you don't wanna spent the extra 300-800$ for those cats.
You also have a 4 OEM cats that you don't have a clue of what to do with once removed (besides store or sell them)
Has anyone ever thought just to cut the new catless xpipe and weld your stock cats to It? Or has anyone done that yet.

Interesting idea but for the TSP headers I'm considering the price difference of $250 isn't enough to make me want to go through the hassle. Their catted version is cheaper than all other major brands catless version.
Stock piping is smaller in diameter than the aftermarket headers. I'm sure a shop can figure it out but taking off the secondary cats and putting them into a pipe might not be a direct swap. The biggest thing I'm thinking is you won't get the benefit of the hi flow cats by putting on the stock ones. With emissions I'm sure the stock ones are more restrictive.

I want to run cats cause I would like to avoid the smell. My other vehicle is catless and I. Think one car like that is enough. I wonder how much the post O2 cats really help with that. This was just an idea I had. I'd like to do kooks headers and kooks green cats, but for that kind of money, I might as well weld in the stock cats to an kooks catless xpipe myself. I'd be willing to sacrifice a little power gain for cleanliness.
