GET RACE-LIKE EXHAUST FLOW

The IAG Performance Equal-Length Exhaust Manifold and Up-Pipe is a great way to increase the horsepower and the torque while improving the turbo spool by 300rpm to produce a race-inspired 4cyl exhaust note. The header features true 304 stainless steel construction along with cast stainless flanges. The header also has a 45mm piping diameter to allow for an unobstructed flow path for the exhaust gases leading to the turbocharger. Because of the free-flowing design, you will see power gains across the entire RPM band. 

The header also features a slip-joint expansion section to accommodate for the flex that is caused by heat cycling and is TIG-welded to provide maximum strength. The up-pipe included in this package features a 60mm piping diameter with a 3-bolt flange, and it will come supplied with a multi-layer steel gasket to provide an optimal seal between the header and the up-pipe.
