It's a sign......truck wants more rumble.
I've had many mufflers since owning my truck trying to find the one that works for me. It really depends on what you're after.....stock volume, medium loud, or loud. Direct fit, welded on, or full system.....straight thru or chambered. Lots of great choices out there. Feel free to search some of my threads on the mufflers I've tried over the past year or two. I currently have the Solo Performance Mach 44 kit and am really liking it. I've had it on 6-7 months now and it's been the best so far. Nice tone, not too loud, and no real drone to speak of.
