Swapped out the super turbos for some ultra flows. What a big difference, sounds awesome ! Can actually hear the camshaft hit now, and may just be me but the car feels faster. I thought it felt slower after i put the super turbos on, but just ignored it thinking i was crazy !

The 2 1/2" super turbos have 2 1/4" internals. The 2 1/2" super turbo offset-in-center-out is especially restrictive the way the exhaust has to flow around the center out pipe internally. On a mild engine probably not as big of a deal but on higher powered engines it will hold down the power.
