Rattling noise and replacing y-pipe

BigS said:
I have the same problem, but by me is the problem the heatshield from the cats.
My dealer told me, i must remove the heatshield and the probelm is eliminated.

My cat heat shield rattles too. They are pretty deteriorated from rusting. We discovered it when installing my exhaust. We put a metal zip-tie on it and it solved the problem but that must have came loose or moved because the rattle is back. It isn't very noticeable though.
 
they put a clamp on the pipe from one of the Y-pipe and now the rattling gone, quick fix for now i guess.
 
I corrected this wonderfull sound of gently fujita f5,purrs beautifull.But the assumption of the whole exhaust is probably better .It just gives the sound.
 
Make sure it's the one that looks like this:

ordered the megan y pipes,
he was kind to call and ask which version i needed.
will install and update on post! thanks for the help
 
Just recieved the y pipe, will install it tomm.
Looks like the welds are done by hand? Is this normal?
Well the gaskets that it came with the pipe looks funky, wonder if i have to get oem gaskets. Also is it ok to remove the y pipe heat shield? I believe it might be better to remove them, since winter is long in syracuse. Lol
 
Installed the y pipe
The box said m2 not megan, but the pipe looks just like the picture above. Everything was super easy except taking the original pipe off.
I saw where the crazy rattling took place. It was on the braided section on the driver's side which tore itself apart, l just hope that the new pipe will get me atleast 3 more years.
Finally rattle free and thanks for the help guys!
 
Did the gaskets eliminate the rattle? I already tried clamps on mine and it only helped a bit.
