Searched quite a few times only found one thread that had one person say something about the sway bar but not enough info, anyway typical thing I have what I believe is a megan downpipe that was made for acd however still rubbed my transfer case. I "fabed up the pipe" with a hammer and not its not touching but still close so I x'd that off the noise list. Nest what I found is that the pipe is just about touching the sway bar , barely enough room for a sheet of paper to fit. The noises all started after I installed Spec-R springs this past weekend. Does lowering the car change the geometry enough that the sway bar would somehow come close to the exhaust? Im going to modify the hangers Saturday for more clearance just looking to see if anyone else has any more info than what I found. (FYI - this happens on warm up and sometimes idle, also sometimes when pulling out in 1st.)

 

The sway bar would rotate so maybe. Anyway, sheet of paper worth of clearance is not enough. The motor and hence the transfer case moves on rubber mounts.

 

Exactly that's what I was thinking , I have urethane hangers on order hopefully I can mess with the hangers this weekend to pull the pipe away more from the transfer case. But seems also it's hitting my sway bar creating this annoying sound.

 

This is the front sway bar with the car jacked up

 

From my experience, the megan DP designed for the 9 has perfect clearance throughout, I would double check that you don't have one meant for the 8's.

 

To be honest I don't even think it is a Megan I think it's a knock off that was installed when I bought the car. What do you think , I think your right saying it's completely wrong idk

 

Solved my problem , with my car on a lift i was able to clearly see the downpipe sitting against the sway bar , was able to use a big pry bar and adjust the exhaust hangers and gave my self plenty of room from the transfer case as well as the sway bar , all this happened from lowering the car also , swift Spec-R , but all is good now.

 

 

Are you sure you have the correct DP for your EvO? I have a 9 & use an Invidia system & dont rub at all. Dont think installing end links will affect the FSB position enough to make a diff w/the rub? (could be wrong).

 

 

Its very possible that DC pipe was just not made properly for your EvO model. Ive got a 9 w/ACD & lowered & my pipe fits w/out rub on the FSB. Now, it does rub on the 2 lateral bars that i had to space down
