I own a 2014 vehicle with a 5.2-liter engine and I am considering buying headers.
I own a Fabspeed valved exhaust already.
I am interested to know whether there is a discernible difference in sound between the original manifold and aftermarket headers. If such is the case, is it only a matter of tone or volume, considering that it is already too loud?
What is the disparity in HP?
Is the effort used worth the outcome achieved?
