There is one thing important thing to say about these mufflers. When you take them apart, there is a very restrictive end cap that can be removed, this could be called a baffle if you wish. Next, there is a core baffle with a ton of tight insulation around it for sound deadening and back pressure. You can remove all of these, or a combination to suite your taste.
I just removed the end baffle and left the rest alone. I can't remember the center core size, but it was very similar to the Krome Works inner core. I figured these would flow very well and wanted to try them on the dyno in different configurations.
I ended up buying a two into one instead and never tried them out.
The picture below shows them with the end caps removed, that is a pretty large straight through design.

"there is a very restrictive end cap that can be removed, this could be called a baffle if you wish" This is what we removed and I called the restrictor baffle, The core and packing were all left as is as we were concerned with noise levels. While I am sure there is more Torque and HP left on the table with a different exhaust system it was not what the customer wanted. As it is now you can ride in 1st gear and with the clutch fully out, hold it about 1500 and go WOT and it picks the front tire up off the ground, then turn around and let it idle around in 1st gear in a parking lot and it just doesn't care. This isn't what everyone may want but its what the customer wanted and so far I think he is happy with it.
