This is the noise amplification device. It attaches to the end of the noise pipe, and is underneath the rain tray on the right hand side of the car.
I had the aluminium LCA installed on the right hand side for a week, and even with just that, I could feel the right hand side of the car was much more stable over the road, especially for sweeping turns that loads up the right front of the car. I could only imagine that adding the spindle would bring it up to another level! Will know by tomorrow when I do the left side too for sure.How do you like them?
I got mine installed at the same time as my LCAs and everything, so I never got a chance to feel them just on their own when added.
