- Wed Aug 11, 2010 11:54 pm #208530 i have tanabe medallion exhaust on my car its an alright exhaust but the only thing is when i start it in the morning it has a vibrating sound coming from it and the only time the noise goes away is when the motor is warmed up i checked under my car and the exhaust is not hitting anything at all what do you guys think it could be????

- Thu Aug 12, 2010 1:34 am #208538 ummm my guess is that the honda tuning when its in closed loop isnt as smooth as when its at normal operating temp..?

...or another out there idea would be the thermal rate of expansion.. when the exhaust is cold there is a gap somewhere but when it heats up it expands and stops vibrating...

- Thu Aug 12, 2010 1:49 am #208539 do you think i should just change the exhaust

- Thu Aug 12, 2010 2:07 am #208541 how annoying is the vibration and how loud is the exhaust?

- Thu Aug 12, 2010 2:58 am #208553 could be the connection from pipe to pipe which started to show wear. Jack your car up and take a look at your system. See where exhaust water is coming out and if your connections are loose.

Question: did this happen when you first installed the system?

- Thu Aug 12, 2010 3:21 am #208557 the vibration noise is pretty loud until the motor warms up but its only at the exhaust end and i bought the car with the exhaust on it already

- Thu Aug 12, 2010 4:02 pm #208630 Your hardware is loose and when the exhaust heats up, the hardware expands and tightens up.

I would take it to an exhaust shop so they can put it on the lift.
