Let's hear some remedies to eliminate LT headers banging on the floorboard.

Mine do just a little bit...but it is worse because if it is not hitting sharply, it is moving just close enough to vibrate against the heat-shield/floorpan as the engine revs up. Sounds NASTY and feels...pretty good! Just kidding. Serously, it is pretty rough to hear and does it only when I really get into it, which makes flooring it less fun.

What are your methods?

 

I put a poly motor mount on the driver's side along with a poly tranny mount. I have no banging issues at all.

 

a poly tranny mount solved my banging issue and i want to do a poly motor mount next just to be special
