Shawn: Probably not in the case of an M, but on racing engines - yes. In the case of nascar stockcars, for example, they use a cross-over pipe between the two headers to create a little back pressure, which in turn, helps with low end torque. Not too important at a super speedway like Daytona or Talladega, but very important at short tracks and road course tracks.

I thought the crossover pipe also had something to do with equalizing exhaust pressure from both banks as well. You will know if you don't have enough backpressure LONG before you warp any valves, etc.
I hate Osseo and I hate everything around it. Fall Creek all the way to West Salem. They all suck. Hills really suck!!!
