I am running the Black Widow Pro Venoms, and really like them. I'm one of the few running a big block in my car (Shafiroff 540 Ultra Street) and recently converted the car over to a complete DSE set-up and had the opportunity to have the exhaust redone.....I did however, keep my Black Widows and incorporated them into the new exhaust system.
Old set-up....
New set-up with DSE Q-link and 3-inch exhaust...
