Exhaust Configuration
I recently purcahsed a 83 blazer with a banks turbo installed. When the guy installed it he left the stock dual exhaust on.It still has a 3 inch down off the turbo,but then he fabricated a Y and tied into the factory dual.I called banks and I can get the correct 3 inch single all the way back but its around 400 bucks.Can any one give me any input on if it will make that big of a difference in performance.Thanks
