Tomei EXPREME Ti Titanium Cat Straight Pipe - Mitsubishi Lancer Evolution VII-IX (CT9A) - 4G63
The Tomei EXPREME Ti Cat Straight Pipe replaces the factory catalytic converter on the 4G63 Evolution VII, VIII and IX with a full-titanium Φ80 mm pipe for unrestricted exhaust flow.
It weighs 0.8 kg against 5.3 kg for the factory part – a 4.5 kg saving – and retains the factory flange pattern, so it works with factory and aftermarket cat-back exhausts.
