I have a similar problem also only that this happens in the rain or if I run over puddle only if the a. c. is on. When the a. c. is off, the car's fine.

I use to get this as well. I think mine started happening after I did the CEL fix on a bad cat. Mine has since stoped thought but I know what you guys are referring too. Its a pronounced vibration that if i remeber correctly that happens under engine load. It shook the passenger seat more than it did the driver seat, or altest thats what it sounded like.

Happened to me for the first time today.... has to be some issue with the catback... I never had the problem with my old HKS but now with my new exhaust I just experiensed it. Something to do with the resonators hitting the driveshaft

i have the same problem..only when the AC is on, in heavy rain it seems. It happened when i modified my exhaust for the qtp cutout. Probably vibration related.

This thread is too funny. I had this problem for a while, but it went away after swaping in my v-band buschur TBE. I never got a chance to investigate. It was the most annoying thing ever.

I'd be willing to bet $1 all of you have an HKS catback or an exhaust that copied the HKS design and they put the resonator in the wrong place.
It's the HKS exhaust resonator rubbing agaisnt the carrier bearing thing on the drive shaft. No amount of adjustment is going to completely fix it. It's a flawed design and HKS should do something about it, instead they say you just need to adjust it more, the resonator is in the wrong place. Hammer it in so it doesnt rub or sell the POS.
I got rid of mine and will think twice about ever buying an HKS part again.

Your issue may not be the same issue that the OP is describing. Take it to the dealer if it's stock. In the case of the original poster with the HKS exhaust.. here's his problem. 1 finger of clearance is not enough, I had like 3/4" of clearance and mine still rubbed. I also noticed it did it much more in the rain but mine would rub going aorund corners sometimes as well as in the rain. It sounds like brakes dragging on the rotor or just a nasty metal to metal sound. I searched high and low and finally saw what was the problem when my car was on a lift. There are someone elses pictures but I experienced this as well. The part of the driveshaft in these pics is supposed to be black.. not bare metal. What's weird is that it didnt happen immediatly after putting the exhaust on the car, it waited about a month to start rubbing. Maybe it is a heat issue, either way I got rid of the HKS, got a Tanabe Concept G TBE and my issue is gone. For such an over priced exhaust (HKS) it should fit like a glove, instead of fitting worse than a ebay exhaust. Honestly I think the reason this hasnt come up before is everyone is too embarassed that they spent so much money for such a POS product. I was that way too for a while and now I just dont care. HKS exhaust is Junk, at least on my IX MR it was.
I called HKS and they insisted no fitment issue with their exhaust and told me I needed to loosen all the bolts and move it right. I had already dont that and told them so and they offered no other solution. If they would have put that resonator 6" back this wouldnt be an issue. Design flaw! my car is not lowered nor does lowering or not lowered affect the exhaust location.

I had the same problems with my HKS Hi power catback. The best thing to do is to just cut the resonator out and weld a 3" pipe in place. It wouldn't hurt to put a 3" flange on it too.
