So i recently purchased a 00 ws6 and I'm looking for some advice on what to do with its current set up.
Its currently running long tubes with a 3'' y pipe going to a single inlet dual outlet flowmaster muffler. I recently removed the flowmaster since it was damaged but don't know what set up to go with.
My questions is should I go ahead and just get another single inlet dual outlet hooker muffler OR would I notice a significant HP difference running dumped true duals with slp LM2? I honestly don't care about looks or sound I just care about gaining the most performance at the strip.
current custom cam specs if needed: .558/.578 lift, advertised duration 279/290, 218/230 duration @.050" lift, 112 degrees of lobe separation.
