Slow to no progress in the last few weeks. At least two weeks out yet before I can finish the exhaust.
I broke down and now I have two Lossa Megaphone exhausts, an 18" and a 12". I originally bought the 18" (Quieter Version of their 18"). This was on the bike when I originally fired it up. I gotta say - I really really like the sound. However, the 18" is long enough that I probably need a hanger from the seat subframe. I couldn't get over it - so Finally broke down and ordered the 12".
I fired it up today and gotta say - It still sounded great. Lighter weight and better integration with the full bike - or at least, what I wanted originally wanted (Something like a short stubby Ducati Pantah 750 TT exhaust).
Comparing the two exhausts, the 18" (quieter version) sounded like a proper Parallel twin - STREET BIKE. Really nice sound.
The 12", still had the nice parallel twin sound, but really sounded more like a racer. Loud, but personal opinion - not radically loud (like some other bikes I've had), not bad. I think this will do. (I am having thoughts of being able to swap back and forth between the two though...)
Here's the pics. 18" Left, 12" Right.
I need to get started on exhaust brackets. You can see the mock up in the 12" picture.
As usual, I like to start with CAD.
Here is the Right Rear Set assy.
As there may be a lot of Vibe, I didn't want to thread straight in to aluminum - so I use SS threaded insert / helicoils.
And I want it to be really stout so 1/4" thick extension, added on to the back side of the foot bracket.
Got a couple of hours in the garage today.
Mock up, with Rubber Grommet for Vibe.
All for now.
