Thunder Header 2 in to 1 or Rinehart True Duals

I was wondering how much performance will I lose taking off the thundeheader 2into 1 which the headers are cracked and I was told they are junk cause they wont warranty them when they crack. A friend of mine has a Rinehart true duals system that he took off and put D&D fatcat. HOW MUCH PERFORMANCE WILL I LOSE GOING FROM 2 NTO 1 TO TRUE DUALS?????

Your probably not going to notice any difference...A set of pipes have to be a certain diameter
off of the head..this is where it picks up it's horse power...they are designed to create a vacuum
called back pressure, or a lack of it..if it is the right size..
so that exhaust gas is not forced back into the head..the tail pipe has less to do with it..ever notice a dragster, there are no tail pipes, it really doesn't need it..just the right size pipes..am I right?
