well 1 i don't think that the IS's exhaust shake or anything because that would be dumb maybe your on bumpy road whenever you see them lol, but IS-F maybe a little because the quad exhaust are just for show they aren't built in with the exhaust they are just exhuast tips built in with the bumperi dont have a IS yet but everytime i see an IS on the freeway i notice their exhaust shake up and down very fast. Lexus probably made their hangers a lil too lose or something. is it the same on the IS-F? any harm in the long run?
