The can you want for that machine is the HPS, get a hold of Big John on here or go to sledheadracing.net (Big John's business) and he'll set you up.

Check all you Heim joints on each end of the tie rods and steering arm mine are worn and sloppy, and also the plastic bushings at top and bottom steering post mounts those get sloppy too.

I like my MBRP, its not to loud or raspy, sounds good.

I liked my MBRP race can on my std 670 too! But, after talking with Scott at HPS and learning that they will build one for your riding altitude I was sold. If I remember right the MBRP did lose a little power as the HPS had no power loss. I added the 670X pipe and HPS can per BJ's recomendation and loved it!!

Yeah, I know what they advertised, but if I remember right it was a slight loss - that could have been at altitude though...........I know one thing for sure, I loved the sound of the "Race" can on the 670.:beer;

Ditto that. I checked mine compared to stock with a DB meter and at idle was only couple DB more and at about 4-5K was about 5 DB more than stock. Lot deeper, throatier rumble though.
