HKS Hi-Power SPEC-L II Exhaust for CZ4A Mitsubishi Lancer Evolution X

HKS’s SPEC-L II Exhaust for CZ4A Lancer Evolution X cars comes in at 9.2kg, which HKS rates as 54% lighter compared to stock. It is built from SUS304 stainless, runs 65mm piping into twin 50mm pipes and exits through 94mm tips on both sides of the 4B11 turbo sedan. HKS measured 90 dB against 84 dB for the factory system, a step that suits an Evo used for back roads and track days more than a quiet highway cruiser, and HKS notes that its Japanese certification covers the Final Edition.

Frequently Asked Questions

Does the SPEC-L II Exhaust for CZ4A fit the Evo X Final Edition? Yes. HKS lists the SPEC-L II Exhaust for CZ4A, part 31019-AM111, for the 4B11 Lancer Evolution X from 2008 to 2016 and notes that its Japanese certification covers the Final Edition. US owners should still check local rules, as Japanese certification does not apply to US law.
How much lighter is the SPEC-L II than the factory Evo X exhaust? HKS lists the SPEC-L II at 9.2kg and rates it 54% lighter compared to stock, so more than half of the factory exhaust weight comes off the rear of the car. For an Evo X used at the track, that saving is one of the main reasons to choose this system.
How much drone does the SPEC-L II make on the highway in an Evo X? HKS does not publish a cruise figure for part 31019-AM111. Its close test shows 90 dB against 84 dB for the factory system, a 6 dB step. Drone depends on gearing, tires and cabin insulation, so interstate commuters should expect more exhaust presence than stock.
Does the Evo X need a tune with this exhaust? No. HKS lists no tuning requirement for part 31019-AM111, and the kit includes no engine management. The 4B11 turbo keeps running on its factory calibration, and owners with an existing tune should tell their tuner about the exhaust change.
How much ground clearance does the SPEC-L II have on an Evo X? HKS lists 125mm of minimum road clearance for this system. Owners on lowered suspension should measure their own ride height before ordering and take care on steep driveways and speed bumps, since clearance on a given car can differ from the HKS figure.
