This kit completely replaces the factory rubber hoses that can expand under boost. We have also relocated the factory blow off valve placement to the hot side tube and gave the re-route a direct path back into the intake.

The hot side tube is 2.5" mandrel bent polished aluminum with no weld joints in either pipe. They are joined by high quality silicone couplers as well as a hump hose in the middle to allow the tubes to properly flex when the engine rotates. You have the option to use the factory BOV, or we offer an HKS SSQ flange, or Synapse Synchronic BOV flange welded to the hot side tube.

The cold side tube is 3" mandrel bent polished aluminum that lines up perfectly with our 3" outlet on our intercooler upgrade. You can still run this pipe set with the factory intercooler with a silicone reducer we can supply by selecting the option below.

The Hardpipe Kit Includes:
- Hot side and Cold side polished aluminum tubes
- All necessary Silicone Couplers
- Hose clamps

Fits: Mitsubishi Lancer Evolution X 2008-2009
