I still thought my mufflers were too loud so I installed Super Turbos. Even though that was quieter I still thought it was too much. Must be the Off Road H-pipes that put out so much sound, not to mention the crower cam discription says "big sound" on there web site. So I did my Mod again taking square galvanized fencing a 2' X5' roll then cut it in half and put each 1 foot roll into each tail pipe and sprayed black barbeque paint on them for camouflage. Muffled the sound to almost in half and still has a roar when wanted instead of all the time. Only 5 bucks at Home depot. Check out my pics in my garage for views of the wire. You can always yank them out for the strip and put 1 screw in to keep them from sliding out. Not for everybody because some people like it loud all the time. Don't you love being deaf when you get off the interstate?
