I won't touch the headers on my car. I've seen other people's nightmares here and on PPBB,with older cars that haven't touched the headers since the car left the factory.

I only have the muffler and for me to say I felt anything from it,would be far fetched. Member Randall_N dynoed his car with a +5hp across the board though,exhaust mod only and it's been documented here.
