Why is the Fulsac no better? It eliminates the "Y" pipe, has a nice radius pipe for the left side, and a straight pipe for the right side. Have had this on mine since 08 and has given me no problems.

I have the Full Sac and it works as good as any other true dual. Rear pipe has a nice radius to it
07 Touring Bikes have a restrictive left muffler and would have a lot more backpressure on that side. Would recommend aftermarket slip on mufflers if going to true duals.

So why is it better than the cobbled job? Seems to me to be about the same.

It would seem to me that the exhaust gases have no where to get caught up in with the Fulsac, a nice smooth flow out. The cut and insert plugs leaves dead end chambers for the gases to get stuck in.

The Fulsac allows the exhaust to flow out the left muffler like it should, not all confused and taking a sharp 90. No exhaust worth a crap has a 90 turn.
When you do the fulsac, you're doing a true dual set-up with 1 3/4" headpipes. You should take advantage of that and add some fuel in with it.

Sorry, they might be over priced, I'm not sure. I got mine from a forum member for around $100...

I'm in this boat with you....I got mine used for $100 also. That plug idea is neat and cheap fro sound but it's a bad area in there for exhaust flow.

Great write up on the home made duals. Most people get true duals to ditch the second pipe on the right side altogether (heat, whatever the reason) Is there any real benefit to leaving the pipe and heatshield other than just for looks? Seems like cutting the pipes closer to the joints and installing the freeze plugs could be made to work and get rid of the rear jug pipe too.
Just asking.
