Definitely get gears and maybe you might be able to hang with him! My friend has an 01 ws6 and when he was stock walked me pretty good. Now he has LT's offroad pipe and lid and I have CB, 4.30s basically and we went from a roll on the interstate, actually a lot rolls one day, and he still walked me. I have raced him once from a dig and he beat me, but I had just installed my gears two weeks before along with a Spec clutch, so I wasnt used to the setup. Get gears, midpipe, DR's shifter and pray he screws up somehow, which probably won't since hes an auto. Have fun and be safe!
