I have 5" chrome truck stacks, 4ft. long, with 90 deg. turn-outs that I installed over the Two Brothers Drag Pipes, 3 header pipes on each side with baffles removed. You can see where they start in post #10 picture, just left of the brake drum and are hidden when wheel is installed. I made my own mufflers (glass packs) inside each truck stack. I get a lot of comments how great they sound (real deep growl) and how big the stacks are. Scares the crap out of the Harleys when I rev-up the engine.
Sorry, pictures could be better.

You can see the chrome strap hanger holding the stack.
Both stacks and my homemade trailer hitch.
Stacks turn out under the light bar in front of the mudflap, but don't block the view of the mudflap.

Can't wait for better weather so I can get some good pictures outside. Right now my trike is inside a plastic tent (12'X 15') that I built around my motorcycle lift. My garage (30'X30') isn't heated and I have a propane turbo heater and a kerosene heater to heat the tent. There isn't a door in the plastic, so I have to cut the plastic to get the trike out. Come on springtime, groundhog said early spring.
