Squeek from exhaust!

[widster]

I fitted a Mongoose exhaust to my car a few months ago. I have been using the car a bit more recently and notice that there is a 'squeek' or 'rasp' noise that happens when revving up or down past about 4300rpm on the rev counter. I can only think it may be the exhaust resonating, a loose baffle or i even thought it could be the TVIS operating? Also, i didn't replace the mounts for the silencer when i fitted it so thought it may be because of this. It's not a particularly unpleasant noise and i could live with it but would be nice to know what it is?

i have eactly the zorst
with exactly the same problem

sure its the baffle
as i have swaped cars and swapped exhausts over. still same problem

looking at hopefully putting my old HKS one on
as its driving me up the wall as it does it a lot

Yes, looks like the Mongoose exhaust may not be that well made then as mine did it pretty much as soon as i had fitted it.

check where the exhaust hangers are mounted, its not uncommon for them to start splitting at thise points and cause a bit of a noise. Bit of welding and all was good with the last one,
