Exhaust for built LS1

I need some suggestions on best sounding exhaust, with minimal rasp when accelerating. I would like a nice deep rumble when idling and no rasp when getting on it. It is a cam heads ls1 car with TSP longtubes, and 3 " off road y. Right now it has SLP loudmouth and it is so raspy it is annoying to drive and sounds like crap. Was considering just swapping resonator with an alternative. Any suggestions are appreciated.

I had the same exact thing as you and swapped the LM1 for a MagnaFlow 14419. The dimensions are almost identical, and it sounds much much better

I'm running this and my exhaust stops right at rear . Has a great deep tone with no rasp
