Why no balance pipe? An H-pipe does wonders for Flowmasters as far as the droning.

 

I have a custom built crossover section. It's in the photo
below with an inside shot as well. I would think that this
works similar to an "h" pipe and possibly better. The
opening is about 1" by 12".

Ok, cool. I saw that, but didn't know if that was actually the crossover or if it was just welded like that to keep the pipes together. That's pretty cool. Personally, I'd just add some bullets in there right after the cats and leave the 1-chambers out back, it sounds nice right now.
