    2015-8-18u2002·u2002The consensus opinion among exhaust flow experts is that any V8 engine will benefit from an H-pipe or X-pipe section mounted on a dual exhaust system. Others feel X-pipes are better suited to free-revving overhead cam V6s and V8s, while H-pipes are a natural fit for high-torque big-block V8 engines that make their power lower on the rpms scale.
