Review on Motorcycle Universal Manifold Vertical Motorcross by Shane Gonzalez

This so-called "Universal Manifold" was a hassle to install, and offered little to no performance benefits in my automotive application. Through trial and error, I found that the manifold actually impeded airflow and hindered engine power. The only positive was that it was made of durable material. On the downside, the design was completely inefficient and not worth the price tag. Save your money and invest in a better aftermarket part.
