I currently have a ITR muffler installed. I have custom bend 2.25" from the cat. Need some advise on how to make the muffler fit correctly. Seems to be too low. I can hear it scrape once in a while. The LS is lowered with Neuspeed 1.75 drop springs. I took off my DTM Dual exhaust muffler because it was too loud on the highway... couldn't stand it anymore!(Sounded great at 80mph, speed limit is 65mph!) Anyone with experience with this set up or suggestions? The ITR is huge! I like the sleeper sound though....

 

there are 2 rubber hangers holding the ITR muffler up. If you move these hangers up higher or relocate the ITR muffler higher up the hanger, the problem is solved
