It doesn't surprise me that the HMF is loud. It seem that they do pretty good research on power but they don't do to good of a job on making it qiuet. But i'm ging to wait for more companies to come out w/ exhaust and wait for a test from dirtwheel or another mag. I think we should have a ton of people send atvsport e-mail to do an exhuast shootout for the Z, but we have to give the manufacturers time.
You might want to wait for a W-B E-Series. They are finishing up on the design as of last week. My experience with these have been very good. You can also purchase 2 different quiet cores that lower the decibels to about 96-98. :wink:
