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.

Having used these Powerflex exhaust hangers for a couple months now, I definitely do feel more vibration thru the whole car at idle. Don't think I will recommend this for a street car.

Thanks for the update. Sticking with OEM equivalent.

Yeah if you find anything that looks OE-like but tougher/stronger, do let me know also.

I went with the HJS hangers for $15 x 2 that weigh just over 10.3 ounces. With the weight the akrapovic exhaust, I could probably get away with a shoelace. Here are a few pics and the part number.

Update to the update. The vibrations turned out to be a dead VT engine mount. Got that replaced with Powerflex engine mounts and all good now. No noticeable vibration or buzzing from the car, be it exhaust or engine mounts. I can definitely recommend the Powerflex exhaust mounts.

the exhaust still moves at wot, it really just limits the up and down movement of the exhaust.

Very old thread I know. Figured still worth an update.

Changing muffler soon and figured replace all the mounting hardware. Decided to try the Rogue Engineering mounts. They use rubber not poly but they are rebuildable and the replacement rubber is $2.

I wish there was a better aftermarket option for the $47 rubber hangers that you need 4 of

Will update with pics whenever I get around to installing (it's getting cold and I am lazy)

those RE pieces look very nice, I have swapped exhaust systems so many times over the years i have a bunch of the orange rubber hangers laying around.

It's one of those things where, my original ones seem fine (no sagging, etc.) but figured while I am up there might as well bite the bullet.

Reviving it again, Redd instead of replacing the OEM orange hangers, did the powerflex EXH033 ones you put in fit pretty well? My OEM ones are pretty thrashed @140k and I am pulling the exhaust apart soon to add vbands to the test pipes. I figured while I'm down there I'd replace them but now at $52 a pop I'm weighing my options.

My PF exhaust hangers have been on the car for 4.5 yrs, 30k kms, zero issues. I haven't specifically checked on them recently because I've not had any reason. They're pretty much set and forget.
