Which one is the loudest and which require a re-jet?

Loudest is probably my Vance and Hines. I want a Yoshi - wanna switch?

They all require a re-jet. I'd probably guess the yosh would be the only one that may not.
Cool.

Not really a fan of v&h's skinny exhaust look.

how big a difference does the rejet make? i didnt do anythin with the air filters yet just put on the jardine system last week and it seems to run fine. sounds great, better than stock can but not stupid obnoxious

Although not in person, I have heard sound bites of many cans and the 2 best ones IMO are:

Yoshi
&
Scorpion

I dunno ... the floats could have worn high and hence be richer than stock to just about be OK.
The pipe alone is 1 jet size up, the air filter is more like 10 up, so you could be fine with pipe ...

I have to agree that the V&H is a bit loud. The Jardine and wyleco are quieter and deeper sounding. Looking at changing Junior from V&H to something else, maybe a Jardine. (Anyone want a V&H complete system with only a couple hundred miles on it?)
