I have a 2000 mustang gt, just recently I noticed that when I rev my engine (not something that I do much) I heard a clunking noise coming from the rear end on the drivers side, the only thing that has been done to the car is it has flowmasters put in and I put in an aftermarket cold air intake. This is really worrying me and I would greatly appreciate some help

 

get under and check to see you have any loose exhaust hangers or is one of the pipes is hitting the frame someplace

 

Ok, I found out that I don't actually have a problem. Sorry if I wasted anyones time

 

Not a waste of time did you find what it was...

 

Well it never did it when I drive only when I was in neutral, also I did check for anything loose, every was ok. But I was told that it's "just the pop of my exaust" I just never noticed cause I never rev my engine I guess

 

Well as long as you think you have it figured out lol . My flowmasters don't pop though they growl , and I don't think id describe them as a clunking sound.

Thanks for the update I hope it is just that.

 

Check where you parking brake cable goes through the eyelets. I just figured out that was my clunk. Just jiggle it and you'll recognize the sound immediately. I'm going to make a general fyi post.
