I want to get long tube headers on my 2014 5.0 but I already have a Corsa After-Cat X-Pipe installed. Would this still work or should I remove the x pipe all together?

I dont believe so but you'll need new cats

X pipe can stay but the cats wont work with the long tubes. If you had shorty's they would.
