I've been searching here and google like a mad man trying to find some sort of solution. Mind you, I haven't been under the car yet, just trying to get some feedback on here from people that may have had the same problem as me.

I JUST installed a Motordyne XYZ Pipe (Straight Pipe) and Megan (insert hate here) resonated test pipes. So, in total I now have my AAM exhaust (was on the car before the rest of the pipes), XYZ Pipe, and Megan resonated test pipes. On to the said problem....

Between 2,000...say, 3,000ish RPM's..**ONLY ON ACCELERATION** I have a strange and very noticeable..metallic, fluttering, ticking, almost a tweeting noise coming from the exhaust. I have to imagine it has to be the Y-pipe or test pipes because it didn't make this sound before.

Like I said, it isn't the common hissing on deceleration..it is only on acceleration. It's more noticeable on hard pulls between said RPM's...very annoying.

Exhaust leak? Bad gasket? Crap test pipes?? LOL.

 

SOS

 

Describing a noise and being able to actually hear the noise, is like giving a virgin a book to read how have sex rather than giving them a porno and showing them.

If you have a noise concern, it's best to have a recording to properly diagnose the concern.

 

My first step would be to get back underneath the car and make sure every bolt is tight.

I would also check all the hangers to make sure none of them are messed up.

Does it sound more like an exhaust movement sound or an actual exhaust sound? Either way those are the first 2 things I would do before going any further.

 

The fluttering gets faster as the RPM's go up. I tried to get video yesterday while driving only to record nothing but some real nice wind noise. It wouldn't do it as I was revving it in neutral which was odd to me. It seems to only do it when I'm at half, and more than half throttle.

I'm going under the car this weekend though, so stay tuned for updates. And thanks for the help so far.
