J Speed Full Isometric Exhaust Manifold For Subaru

Completely equal length with all four volumes designed to be the same up to the gathering part! Demonstrates smooth power from low rotation to high rotation without exhaust interference. By adopting a 38φ stainless steel pipe, big torque is generated from the low speed range. Easy replacement type up to the support pipe flange for installation. It's a little expensive, but it's a recommended item by Masashi Ishida, who has excellent effects. (Oil pan with heat insulating tape, for wiring)
