With this exhaust manifold, you can expect a more aggressive exhaust note, with improvements to both horsepower and torque. Additionally, this exhaust manifold will accept the stock uppipe, as well as a number of aftermarket uppipes that still utilize the 2-bolt flange. 

Included with the HKS Stainless Steel Unequal length Header is a pair of new manifold gaskets, a new uppipe gasket, and some heat wrap with a pair of worm clamps.
