Header Shootout ! - MAC vs JBA vs STOCK
8 Attachment(s)
Summary: This article shows a comparison done between the MAC, JBA, and stock headers your Mustang. Details: Both test were run on a STOCK 5.0 engine. All the headers tested are SHORTIES. The chart shows that the MAC Equal Length shorties of 1.5" and 1 5/8" deliver the most torque and HP. On a NON Stock motor the 1/2" headers might be too restrictive. The JBA headers (most expensive of all) are the bottom performers on both charts. |
