making the piping fit all the way back is going to be one hell of a problem.
and because of the crossover, it will always sound bad because the pulses will NEVER line up with one another. the f-body 3800s dont have this problem because they can actually make equal length headers.
we have a winner. equal length piping is an absolute must or its not gonna sound right.
