Got my Hushpowers on but the muffler slipped on the hanger and burned the rear valance a little. Would those plastic wire tires around the hanger keep that muffler from slipping?
if the connection at the over the axle pipe is tight it shouldnt move at all. those mounts are pretty good actually. iv had my exhaust on and off my old car a few times and twice on my new car with no issues like that.
It's the very back hanger. The muffler will slide on the hanger and the tip hits the valance. You can slide the muffler back and forth by pulling on the tip.
I torqued my exhaust clamps to 35 lbs-ft and they have stayed centered in the rear valance with no movement at all. I don't think you have yours tight enough.
I just found out Flowmaster includes hanger keepers to keep the mufflers from sliding on the wire. Trouble is, I had a shop install these as I also had them install the Lethal over axle pipes. I couldn't get the car in the air far enough to get the old exhaust off. Since that was two weeks ago, those keepers are gone. I know what they look like now, just need to find a set or call Flowmaster and see if I can get some.
i have flowmasters and dont have this issue. a shop installed your mufflers right? did you double check the connection to see if it is actually tight? or are you just saying they are? if they are tight enough your mufflers shouldnt move period. those hangers are just supports. you get the connector snug then move the muffler around to make sure the tip is where you want it then tighten the connector. no keepers needed at all.
