well i have decided to rid the flw master cat back (too restrictive for my set up). i am contemplating between the mufflex set up or some true duals. what do you all think.
thanks

Duals are cool,but you have to dump at the axle,I think you should go with a 4'' Mufflex all the way.I may do this in the future too.

 

thanks. also i think they say that the true duals resonate a bunch!

 

they both drone. the mufflex pops a lot if you don't have a cat and the duals with drone at about 2200-2600rpm.

I think the drone with duals will depend on the mufflers used.

With the Mufflex, it doesn't pop without a cat. Mine doesn't. If you're getting a lot of popping, check your tune or look for header leaks.

I have a 355ci LT1, 306 cam, long tubes, 3" y-pipe and a 4" Mufflex with Spintech single in/out muffler and some custom tips (pic1 and pic2) that Denny made for me.
