Larini Systems is one of the world's finest resources for high performance, classic and sports car stainless steel exhaust systems. Every Larini System is a combination of precision engineering, aircraft-grade stainless steel and elegant design. A Larini System is the natural choice for anyone looking to improve on the aesthetics, acoustics, or longevity of their current exhaust system. With the introduction of the Charge Cooled Supercharged V6 engine on the Evora 400 (onwards) and the Exige V6 380 onwards, Lotus also introduced their new 3" exhaust systems.
The manifolds however have stayed the same original Toyota parts with the pre-cats which act as the main catalysts. Besides being a rather small diameter system for such a high power car, the pre-cats don't do anyone any favours in terms of flow. Any flow practically stops at approx. 5cm from the cylinder heads..

Larini developed a new 3" exhaust manifold for these High Power cars with larger diameter primaries ending up in a 3" catalyst connection.

These manifolds are supplied including 4 Oxygen Sensor extension leads to allow you to place the oxygen sensors in the correct location on the manifold.
