I think he was referring to the HD SE High-Flow Exhaust system, which you cannot use the SE Street Cannons for because they removed the CAT from the head pipe to the SE Street Cannon mufflers for that particular system. He wasn't talking about after market head pipes.
I ordered the full high flow system with a 114 kit last week. Bike is being assembled now. I'll post some vids when I get it back. As far as "seat o pants" feel I don't think the full system vs just the mufflers would make any difference on an otherwise stock bike. I really don't expect to see a difference with the 114 kit. I went with it because I hate the look of the stock headpipe and even though harley did a nice job of controlling heat with the M8 cat converter, I still want it further away from me.
Any update on this? I am very interested in this same set up. Thinking of doing stage IV with this exhaust to get the 7 warranty, I know i can get some much more out of an after market exhaust and tuner but 115+ hp and tq is plenty for what I want.
it would be nice to just get the header pipe and use the street cannons we already have and have to get the complete exhaust system for 1300
I found out just now that you can't do that. The Header pipe/SC's are a different size and don't work with the regular SC's. What a bunchafukinbullshit!
