I had the same problem when I did my LT install, first I took a pry bar and tried to bend the y-pipe...that gave me a little clearance but it still hit so I went and bought some heater hose and some stainless band clamps and slit the hose and wrapped the pipe where it was closest to the floor board to give it kind of a cushion and it did the trick, now I have been driving with it for about 8k miles w/ no prob and no banging and it only cost me like $10, hope this helps

on my friends car when his x-pipe hits the floorboard it bounces repeatedly, a lot of it depends on your engine rpms , how close the pipe is to the floorboard, and how bad your mounts are. id do the heater hose thing or the header wrap until you have the time and money to replace the mounts.
Heres my experience with y pipe banging. I tried all of the above solutions.
-Bending / readjusting the pipe helps, but in my experience did NOT solve the problem.
-The mufflex y hangar thing, helps, but again did NOT solve the problem completely.
-Poly motor mounts helped the most yet, but still didn't stop the banging completely
My final solution was the heater hose! It works great and have run it that way over 10k miles. I don't like it, but it works.
I think the reason I have had such little success with the other methods is because I have so little clearance in the first place (1/4")

I had my mechanic weld in a little peice of metal kinda like a support and it stoped it....it was free cause it took longer to put the car in the air than to actually do any work.

You need to buy some DEI header/exhaust wrap. Thunder Racing has a bunch of it and a sale goin on right now which is cool. wrap that around a few times where the y-pipe hits. Take two 2.5" hose clamps to each end of where you wrapped the pipe to hold the wrap in place. Then cut out a short piece of large heater hose, flatten out with a vice or somethin, and run 3" or 3.5" hose clamp through it. Now put that over the middle of the exhaust wrap and tighten the hell out of it. Go for a drive and get the exhaust hot. Then get back under and tighten down the middle clamp again as the heater hose will have gotten hot and bend a little more. If you don't retighten it, your middle clamp with the hose may spin upside down over time. Also, over time mine sometime slides out or the clamp eventually cuts through the hose. I like it TIGHT!!
This is how I did it and it works great. I hope this helps
oh yeah, I did have to use a large breaker bar though to bend down the pipe so I could squeaze the hose in there
