X pipe and 518 overdrive

 Anyone here have this combo, I'm thinking tti system but might need to go with the h pipe.

I just installed both this winter.  Fit was pretty good, better than the old dual exhaust.  Mine was on a 440 and I got the shorty tti headers with the x-pipe system.  The x is well behind the transmission.

  I'm curious to know what your e exhaust setup was before  such as size and type of mufflers and if you noticed any drone added from the x pipe.

The reason I ask is I had dual exhaust and then added a h pipe, I noticed not so much of a drone but definately a little bit more cab noise in the lower rpm.
