    I get a weird sound, that I have happened to notice the past few work days when I leave work in the evenings (probably because I have my windows down), that my car makes a funny "metal rattling in a can" noise when it hits 2000 rpm. I never noticed anything of the sort before. It will only make it when it is in gear, meaning I can hit 2k rpm in neutral and the sound doesn't happen. Any ideas what it could be? It sounds like it could be coming from the drivers side, halfway back or further. I have FRPP GTA's.

    Yeah I have it too, its only on acceleration, around 2800 rmps, I thought it was a loose clamp on my SLP LM's but I checked it and they are all tight. I was thinking it was the pipe hitting the car, and at that rmp is just right to make it do it. I would love to make it go away.

    My new Bullitt is making a metallic sound at 2200 rpm. Its worse when the car is up to operating temp. I do hear it in neutral if I slooooowly raise the rpm and keep it there. It really becomes audible up against a wall.

    I've had some history with the dealer I took it to but they did not want to spend any time on it since I did not buy it from them. I bought it from a dealer 200 miles away. I'll post any info if I find the cure.

    What year cars do you guys have??

    2007. Right, I notice it when I leave work I think because I am in between a bunch of walls. Well, at least I am not the only one. :shrug:

    I do. I have the frpp gta's, but they have been installed for over a year, and I just now noticed this noise. It doesn't quite sound like resonance. It has a higher pitch.

    Got mine in Feb of 05, and axle back was on in Mar, It used to spit alot with a cold start, but almost never now. The rattle sounds more of an undercarriage vibration, then coming from the exhaust itself.

    Gonna see if I can get an audio clip of it.

    I noticed a similar rattling not long after I put on a set of flowmaster axle-backs, the offender turned out to be the driver side tailpipe coming in contact with the differential housing. The clearance is pretty tight (right at the bend before the pipe goes up and over the axle), it got closer after I made some adjustments to center the flowmaster in the rear fascia exhaust openings. If would only do it sometimes, not all the time, typically when it was cold out.

    That actually might be it. The sound tends to go away after the car heats up a bit, and that is the right RPM range. Guess I will be taking it in for a looksee.

    My car is an '06 GT with a 5spd. Unfortunately it is pretty much bone stock except for the K&N drop in filter. The TSB mentioned above sounds like the problem my car is having. Thanks for the info. I will mention the TSB to the dealer when I take the car in on Thursday.

    I had the same issue with my 2005 Mustang. It was not that plate that was making the noise though. One thing that you guys should check (especially if you have changed your exhaust) are the hangers on the mufflers. The center (where the exhaust hangers mount) are rubber. But as the exhaust shifts back and forth the hangers sometimes rub against the metal portion of the mounts. You all should check that out cause that was the noise on my 2005 GT. I just bent the hangers slightly and it took care of the problem.

    Hope that helped.

    Where did you find this at? The dealership says that there isn't a TSB for this issue, and no matter how much I tell them that there is, they don't think so.

    Anyone have the CHE K-Member Brace with the Torque Limiters with the rod ends? I've got it and it makes a LOT of noise. I just wanted to see if it was normal. I'm pretty sure it is but wanted to make sure.
