I own an '05 Mustang GT, I have written about this problem on this site before (prior to the weird metamorphosis of the site), but neither myself, nor Ford, nor my aftermarket dealer can figure out this problem on my car. I've owned my car since July of '05 and had no troubles whatsoever until after getting a Magnaflow (not magnapak) exhaust kit installed in February. After the installation I noticed that intermittently I would hear rattling, obviously unnatural noises coming from the driver side rear of the car - so I of course attributed it to the Magnaflow, brought it back to my installer, he observed it, had a new one ordered, and installed the new one - and the noise is still there. I brought it to my Ford dealer, they kept it for a week and had specialists work on it, replaced shocks/struts and other things, and absolutely could not figure it out and so they blamed it on the Magnaflow and told me to take it to a team of mustang exhaust specialists in my area in south Florida, I went yesterday, they heard the noise but are "99% positive" that it is not the exhaust as they could find no defect with it whatsoever and said the chances of 2 defective magnaflow exhausts is zero. They did say that my transmission sounded "mangled" but could absolutely not pinpoint the noise. I have an appointment to bring the car back to Ford on Tuesday... but does anyone think that this constitutes a lemon? Does anyone have any ideas on this? For reference... the noise happens roughly 1-3 times per driving from one place to another, and happens primarily in first gear when going slowly and then again in 4th and 5th when driving fast on the highway, and happens anywhere from just 3 or 4 seconds to 30 seconds at a time, and can be heard MUCH better with windows up versus down. Any help would be greatly appreciated.. thanks!

I don't know if this would be grounds for the car to be classified as a lemon but it sure would be annoying!

no that is not considered a lemon

I remember your previous posts. Do you still have the original exhaust? I know it will be a pain and cost some extra $$$, but I would have it installed and attempt to let Ford find the problem. Since you've changed the exhaust, it would be logical to blame the problem on it, even though it may be something else. I don't see another out, since it could even be a structural issue.
