Putting the Muscle back into Classic Cars

Changing the Headers on the Trans Am


It is important that a motor can breath in order to make power and the manifolds on the Trans Am weren’t allowing it to do that.  Some Ram Air Headers were ordered and then Port Matched in order for the Pontiac motor to breath and produce that extra bit of power.  This combined with all of he previous work more than doubled the power of the Trans Am.
