i installed the bump stop and got more vibration then before. sounds like its a 50/50 if it will work for people.

i may not have perfectly installed mine, so i would hesitate to say it is a bad part or that someone should not buy one.

My exhaust was banging alot. the y was close and the exhaust shoppe did heat and bend it a little. the design of the 4th gen is pathetic for a dual exhaust and is one reason why I dont think ill ever love my Camaro.
I purchased that hangar but realized that my original pipe from the cat is 2" or so and the Y was installed further back from where it needs to be installed. I used header wrap around the pipe and installed the clamp. It works absolutely beautiful. Any of you who claim this part is garbage are seriously retarded. it works as intended and for $40 its quite a deal. My vibration was eliminated 95% only slightly on a rough surface would I feel anything at WOT in first.
The downsides of installing it are that it forces the pipe to hang low. since my car is lowered I did just get over a speed bump last weekend i didnt notice and it slammed my exhaust pipe. it smushed the hangar backwards so I need to re-bend the thing. On the bright side the exhaust was hot so when it hit the speed bump I think it bent the top of the pipe against the floor some more so now there is no vibration at all . Go figure. I planned to have my exhaust guy fix it but I'm waiting on a seller to hook me up with stainless headers and new Y with cats so I'm just not bothering with it.
I wish there was a headers with 2.5 inch collectors and 2.5 inch Y. unless you are over 700 hp 3" is just overkill.

with an exhaust that is max 3 and a half inches you can put a metal zip tie in the whole of the mount.I was not able to use a metal zip tie due to the size of my exhaust.This modification has been there snug for 2 years with zero vibrations and zero noise. this is for sure sticky worthy

or ya can just install the bbk headers and the poly motor mounts and be good to go.
i know the poly mounts are a pain(i did mine on my back under car)but if your going to do headers,do the mounts !!!

When you install Longtube Headers, you really should take the time to upgrade your motor mounts to either Polys or Solids.
Yes, they are a PITA to install, but this is the proper way to ensure the torque flex of the motor won't allow the exhaust to bang on the floor pan.
Any other method is simply a remedy.

It wasn't that long ago that the large steel cans were used for vacuum assisted headlights.
I've also used the 12 oz cans for overflow at the track on cars that never came equipped from the factory with an overflow. Some tracks (depending on the tech inspector) frown on that now.

went by my exhaust shop 2 weeks ago and they modified the y pipe and the bang is gone! I will get some poly engine mounts when I do the engine swap. They charged me 80 bucks but what the hell at least it doesn't bang anymore

Does a y-pipe add much power?
