I purchased both the front and rear sway bars for the 2004 TL to install onto my 2004 Accord. I took it to a local Honda dealership this weekend to have it installed. They installed the rear one with no problems except for the fact that a part of what holds the muffler up is rubbing against the bar. I held off on installing the front as they told me it would require dropping the chassis of the car in order to get to the front sway. Is that correct? Also should anything be rubbing against the sway bar? TIA.
