Update:

Got the pipe and installed it. Rode around a few miles... it sure is alot louder = less restrictive. But my gas throttle/jet still bog at start up. Idling fine, but it takes some full throttling to get the gas flowing before it reeves and pick up.

I replaced the 40 idle jet with a 45 when I put on a BBK and it helped it start and idle much better . Any bogging is BAAAAAAD !!! Upjet before you have a seize !!!!
