Not many companies still make catted x-pipes that I know off. ESS used to make one but now the only one I know of is the AFE x-pipe. Ideally the AFE xpipe and a test pipe setup withe the secondary cats would be pretty close to the same. High flow cats are normally 200 cel which is the same as the secondaries.
