Has anyone heard or had any experience with these dynatech split-flow race mufflers? I know they are a straight thru design but not sure what they sound like. I saw them in Jeg's Catalog. They kind of look like Borla mufflers.

 

They are REAL loud. Aren't you talking about the Dyno-max ultra-flows? Don't know. Dynomax makes a muffler called bullet, but they aren't street legal, they ultra flows are, and they sound nice, but would be kinda wierd without true dual exhaust.
