HMF exhausts

hey, I was wondering if anybody knows where in canada a guy could get a HMF utility exhaust pipe for a '01 450es. SOmewhere in Alberta would be even better. Also, if anybody has any stories on any exhausts that they have tried and liked/disliked that wold be great. I've read some of the posts and it seems that the HMF get pretty good reviews. Has anybody had any experience with the FMF powerline series exhausts? Would like something that isn't tunable as it seems that they have problems with getting clogged up with mud. Thanks in advance for any replies.
