Hey guys I've been having a small problem when turning left through a particular (rippled) intersection going 20-30 mph. (Yes I have searched.) It is coming from the rear of the car and is has a "clunk clunk clunk" noise. I thought it might of have been some worn struts before, but we just got done installing a brand new set of Tokico Illumina's on stock springs on setting 3. I've also installed a Warpspeed Y-pipe and Flowmaster 60-series (in terms of exhaust). I was thinking, is it possible that the exhaust might be hitting somewhere? I installed the pipe myself but paid a Meineke shop to install the muffler using the stock brackets and they also did a great job welding.
Do you guys have any ideas? I appreciate all your help in advance.

 

Could be the catback hitting the rear beam since you said the sound is coming from the back... or it could be your cv-joints if the sound is coming from the front... or if not sure maybe a bad hub

 

Check your trailing arm in the back. Your exhaust might be hitting that when you take those left turns.

 

Thanks fellas. I'll check that out when I get some time to get under it.
