Default Driver side poly mount installed, TSP y-pipe hitting floor now

Hello everyone. I installed Hooker longtube headers along with a texas speed catted y-pipe. My engine was sagging a bit which was causing my header to rest on the k-frame. I purchased poly motor mounts to fix the issue. I just finished the driver side, which gave me enough lift on the engine to clear the k-frame. I took it around the block to try it out, but noticed that now my y-pipe is hitting the floorboard on the drivers side. I can see a clear rub mark exactly where it is hitting.

A couple questions. Will installing the passenger side poly mount fix the y-pipe banging on the drivers side? I used the clamps that TSP provided, which from what I read aren't the best exhaust clamps. Will changing out the clamps with better ones fix the issue? I did some googling and came across a product called the Mufflex y-pipe bump stop hanger which looks like it just bolts on underneath the car on the drivers side. Will that part fix my issue? Thanks for reading.

Put the other motor mount in and see if it still hits (probably will) then just loosen the clamps and readjust the y pipe. That should fix your dilemma.
