Show original supplier description
The Artec Performance Mitsubishi Evo 4-9 4G63 Direct Replacement Exhaust Manifold is precision engineered for enhanced performance and durability. Constructed from investment cast SUS347 stainless steel, this manifold is designed to replace the factory unit without requiring extensive modifications. Featuring 33mm ID runners, this manifold maximizes exhaust flow, contributing to a sharper throttle response. It offers direct bolt-on compatibility with stock frame turbochargers and includes provisions for retaining OEM or OEM-style heat shields, ensuring a clean installation. The cast construction allows for smooth merging angles and eliminates restrictions found in tight radius bends, leading to consistent performance and improved heat dispersion. Artec's design addresses common failure points in factory manifolds, where limited runner merging can lead to concentrated heat and cracking. The easily accessible bolt locations and straightforward installation are designed to be completed in approximately 10 minutes, making it an efficient upgrade. This manifold is designed and tested in Australia and comes with a lifetime warranty.
