How can I suppress the sound of my aftermarket Y pipe hitting the sway bar?
I got creative this weekend and decided to tackle this problem again. I previously wrapped the Y pipe in aluminum foil for cushion, but it was not good enough. I jacked up the car with my floor jack and then got the Nissan scissor jack and jacked up the Y pipe a little bit. Now I had a little room to work with. I took an old sock, cut a little less than half of it off and wrapped it around the sway bar tightly. I held the tight wrap in place and then wrapped duct tape around the sock. I followed up with wraps of aluminum foil around the wrapping. I let the pipe down with the scissor jack. There is still an inch clearance when the car sits. But now when I accelerate, the problem is alleviated, the pipe just rests on the bar and all of the noise and rattling is absorbed and is not felt. So, for all of you with the problem, this may be a solution.
