The OEM size of this part is 1.5″ = 1.77 inĀ² which is a major restriction BaseMax is a service based part that requires a core be returned. We take your core and bore the Exhaust outlet to 1.75″ and port blend it into the rest of the base. This keeps the flow reduction close to 15% which is vital for making maximum horsepower. From here the exhaust enters pipes with a 1.75″ ID which perfectly matches our goal. For comparison the flow reduction if you left the 1.5″ restriction would be an almost 40% reduction in flow.
