[Shortbus]

Its just a single exhaust with a dual outlet on the muffler and its only a 4 cylinder. I can't believe you would actually notice that much of a difference, or be worried about it for that matter. The left outlet may have to travel 8 more inches than the right side to the exit at most, I guess it could cool that much more in such a short distance, but its definately not a problem or anything to worry about.
