i certainly don't mind going louder at all, in fact that's kinda what i am looking for, i just want to have it sound smooth still.
You can't compare a Spintech to any other muffler. It's not a straight through, its not a chambered muffler like a flowmaster. It's just different. Every muffler is going to crackle or pop at a certain RPM with LT's and no cats. Mine doesn't do it often enough for me to notice and I have LT's, no cats, and full 3.5" exhaust.
