I was running my stock 3.8 with a 4.10 rear end. I had Whisper lid, WS6 ram air hood with ram air box, MSD Coil packs, headers, 3 inch y-pipe w/o no cat, 3 inch S pipe, 3 inch I pipe, and a Flowmaster 80 series with 3 1/2 inch tips! It sounded so mean. I was also getting around 28 miles per gallon in the city and 32-34 mpg on the Highway! I would drive up to Jersey from VA beach with only using 1/2 tank of gas. It was 260 miles to my parents house! When I did the built motor I was still getting 25mpg in the city and around 30 mpg on the highway!
