Exhaust help?

I have just got my exhaust on and I can't handle the sound. Its a 2005 HD 6.0 With S.W. Long tubes into a magnaflow X into bulletts. It has 3in mandrel bent pipe all the way dumped over the axle. My proble is that it is to (poppy) around 3 grand @WOT it sounds great and I don't mind the loudness it just sounds like sh**. any suggestions would be great. I was thinking of adding some magnaflows in front of the bulletts or some hoolers

The 22" magnaflow will quiet it down quite a bit. I changed from a flowmaster to a magnaflow and not only did it shut it up, but it also picked up .3 in the 1/4. And as far as the cam goes......can't go wrong there.

three inches is a little big on a true duel setup. everyone seems to go with 2.5 inch pipe when they go true duel. not sure if that would take care of your problem but it could have a little to do with it. cats might help too.

Is the popping only when your decelerating?

The problem is youve only got bullets on not an actual muffler swap em out problem solved

So you got the dual in/dual out muffler with built in X-pipe? If so I would try two things! First cut the cats off. I just did LTs,cut cats,dual in/dual out stainless Magnaflow(22" 5x11 2.5") also went with mandrel 2.5" all the way around. I havent got the tunrdowns on yet so its just staright muffller and Im not having that problem at all BUT I know a guy witht he same setup except he has shorties, he has cats and is runing tips. It sound like a fart/popping. So what I would do is cut those cats off if you can. If you cant cut the cats off I was told by a local guy who mainly installs Magnaflow and he said if you do an H-pipe before the muffler obviously and that along with the built in X-pipe with take care of that fart sound! On my setup the only popping I get is if I run around 6000 rpms for a bit and on deceleration it pops a tad bit but nothing that isnt normal!
