What Are Long Tube Headers for the 5.7 Hemi?

Long tube headers are custom exhaust manifolds that replace your stock manifolds and connect directly to your exhaust pipes. They provide performance improvements by allowing your 5.7L Hemi to breathe better.

The longer tubes on these headers increase the velocity of the exhaust gasses exiting the cylinders. This helps scavenge the cylinders more efficiently, reducing backpressure. The smooth radius bends also minimize turbulence, allowing the gasses to flow freely. The end result is more horsepower and torque, especially in the mid and upper RPM range.

For the best performance, choose headers with 1 3/4-inch to 1 7/8-inch primaries and a 3-inch collector. Larger tubes won’t necessarily increase power and can reduce velocity, while smaller tubes may restrict flow. Stainless steel headers will last longer and resist corrosion better than mild steel.

Installing long tube headers requires removing your stock manifolds and exhaust system. It can take 6-8 hours for a shop to complete the install. You’ll need to have your ECU reprogrammed and possibly retune your fuel injectors. The improved breathing and reduced backpressure may throw off your air/fuel ratio.

Long tube headers are ideal if you want to maximize the performance of your 5.7L Hemi. Paired with a high-flow exhaust system, cold air intake, and performance tune, you can gain 15 to 25 horsepower. The roar of the open headers may even put a smile on your face every time you hit the throttle!
