Guzzler- Mine is setup like yours: PCIII, Stucchi Crossover, mufflers, and K&N Filter.
The Magni looks great but I am not sure about the "break your back clip-ons".
Yeah I believe they are a fair bit lower than stock.
Don't know that my neck and back could handle the lower bars either!
Funny thing is much as I like the Magni everytime I look back at the little screen that came with the bike I doubt I could justify the expense of the Magni.
She does look good as is!
Cheers Guzzler.
