I am looking to put a new true dual exhust on my 2002 FLHT Standard 95 ci. with Mukuni. Does anybody have any suggestions regarding Thunderheader v.s. Rinehardt or others. I have been told that the true dual Thunderheader does not have enough back preasure and can create flat spots on the dnyo run.

 

I've heard that any true dual system robs you of torque unless you have a big, really big build.
