for SS this exhaust is pretty nice for the price and its FULL Titanium. About the V config and how you should run duals. What about 3kGT's and Stealths? They do not run a true dual system and most go for the single exhaust when modifying anyway. Ash is right about the A/F's and since you can control each cylinder bank independently with dual wideband's and Zem or Aem or Conzult.
