***this probably only concerns people with aftermarket ypipes and exhaust that have trouble with their bpipe shaking under any circumstances***

well after changing my oil i noticed that i needed to change my rubber mounts or hangers for my y pipe b/c they were so streched as u can see in the pics...here is the b4 and after pics...after i changed my stock rubber mounts to these http://www.courtesyparts.com/Merchan...de=20651-NISMO

my b pipe does not shake rattle or move at all except if you really put some force into it.

hope this helps who ever has the shaking pipes under the car problem!
yes they are expensive
b4

after

 

You can get those hangers at auto parts stores. And I'm sure much cheaper than that. Good find though.

 

i know that other org members have problem with this but i just don't remember who...but anyways hope this helps some1 other than myself
