I ran the specialty can on my proclimb last year, about 600 miles. I never had any issues with it at all. It's definatly louder than the stock can, but not super loud.
I know how the jaws sounds on an M7 and M1000, how is it on the proclimb? Im guessing its pretty close to the same. I have a Skinz super Q on my M8 thats pretty quiet compared to the jaws.
I think everyone forgets how difficult it is to put a can on a cat 800 and not lose HP
I have a buddy running a box stock proclimb and another running a jaws can.
Its simply remarkable how much stronger the stocker is compared to the one with the Jaws can.
most cans you will lose HP with the highly ported new cat engine 2010 and up.
the only can I have looked into that equals stock HP on the top end and gain 1 or 2 in the mid range is the Cutler can. (CPC racing)
now please remember i havent lookd into it for some time but i wouldnt buy a can for the proclimb without a dyno sheet.
