Now available with 2.5” outlets, these LS exhaust manifolds from Hooker offer improved flow and hug the engine block to be suitable for a variety of replacement and engine-swap applications. Their contoured design shunts the exhaust directly to the exit port for improved flow, while the cast-iron construction offers years of leak-free performance—with less under-hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.
Five finishes available: Natural Cast (8502HKR), Silver Ceramic (8502-1HKR), Black Ceramic (8502-3HKR), Titanium Ceramic (8502-4HKR), and Cast Iron Gray Ceramic (8502-5HKR).
