Rear clunking
I just had H-techs and Illuminas installed and I'm having clunking sounds in the rear when I go over bumps. I'm not talking about pot holes, rather large pavement irregularities where the whole rear is going up and down. The odd thing is that I was hearing this sound before the installation. I figured it was blown rear shocks, they were blown, but clearly that wasn't the sole problem. Sometimes the clunk can be felt and transmitted through to the middle of the cabin. Also, it is often several clunks. Like "clu clu clunk!"
Any ideas?

Do you remember how it started clunking?

you sure your spare tire is bolted in tightly?

Check your exhaust clearence where the muffler and bpipe connect. I had the same issue and though it was my shocks but ended up being my exhaust hitting the car. Check to make sure that all the rubber supports for the exhaust are good and dont bounce to hit the car. Check from ypipe all the way back.

Also, take a look to see if the heat sheild is broken. I had that experience the weekend and it made a "bu-bu-bump" sound inside the car (and "ting-ting-ting" with the windows down). Take a look just in front of the gas tank. Mine was completely in two and the small piece hanging from the exhaust hanger was bumping the rest of the exhaust.
Hope that helps. Good luck!

well, I sure hope you find out what it is.......and when you do, please tell me!!!!!!!! LOL, mine has been doing it ever since I put my h-techs and Illuminas on, I figured it was my bumpstops, but then realized it was doing it even on bumps I know it didn't bottom out on, this past weekend, I took my rear seat bottom out, removed the black cover going into the trunk, and removed the plates covering the struts so I could make sure the nuts were tightened on the strut mounts. That wasn't the problem, so I'm gonna have to go deeper into the problem as soon as I can, I know I'm not putting it back together till I find the problem though. Love the ride, the bumping is a little annoying though.... I will let you know if I find out what my problem is, but it will be a few more days because of work. good luck

Well, I'm pretty certain the sound is the exhaust. For a while now I've noticed my exhaust clunking and my muffler hanging like this:
I noticed the rear driver side rubber hanger was soft and worn. Today I jacked up the muffler, replaced the hanger and when I let the jack down the muffler assumed it's hanging position. This leads me to believe something is broken or loose sooner down the exhaust line. I'm taking my car in for other repairs Monday so they might be able to figure this out as well.

just finished taking my rear shocks off and cutting the bumpstops. After I reinstalled them the clunking is still there. I tightened the top hat bolt too, so its not that. GOnna empty my trunk out tomorrow, hopefully find something there, I looked underneath the car, didn't see anything......sigh. Hate stuff like this....

i have that same problem. the exhaust hanger is off the exhaust pipe in the middle of the car. i just put a hose clamp around the exhaust pipe and tie wires from the clap to that rubber hanger. now my max purres like a caddi. make sure you tighten the wire to clamp very tight, so there is the same clearence on both sides of the pipe. it's not hard it took me like 15 minutes.

just to make sure it's the exhaust hanger, jack up you car on the right rear of the car about two feet. get under the car and look at where the right rear wheel is, follow the exhaust pipe right where it gets close to the car chassie, thats where the clanking was coming from on my car.
one more thing, do you hear some kind of vibration from the rear of the car when you excelerate at low RPMs?
