HKS 95-99 Eclipse GSX Hiper Exhaust
The HKS Hiper Exhaust is a full cat-back system designed exclusively for the 1995-1999 Mitsubishi Eclipse GSX. It replaces the stock exhaust from the catalytic converter back with mandrel-bent piping and a single large canister muffler for substantial power gains and a deep aggressive sound. This setup reduces weight while improving exhaust flow and throttle response on the 2.0L turbo 4G63T engine.
