These Powerflex bushes are only used at the rear muffler section, not the front. So the front isn't affected. It does reduce a lot of movement in the muffler section tho. Which brings me to my update.
Noise - There is no additional noise during driving. However, there is an intermittent faint split second (maybe 0.5s?) buzz when the engine is transitioning from very low rpms to idle. It seems to be random and I can't replicate it, but it was not there before this mod.
Vibration - There is definitely more vibration from the exhaust, felt thru the seats. Its not very bad, I liken it to putting your finger on your wrist to feel for your pulse. It's faint but it's definitely there. I will probably get used to it cos I do enjoy a more feelsome car, but if you want ultimate comfort then this may not be for you. Do note that I have zero cats or resonators, so you may notice less vibrations with a stock exhaust.
Harshness - No harshness to speak of.
