Differences Between Lotus Exhausts From Janspeed

Motorsport silencer supplied from 1996 – 2000

This was the very first aftermarket exhaust sold by lotus for the MK1 Elise as an O.E. upgrade, designed for the Sport 135 kit, the silencer could also be fitted to standard cars. This exhaust was manufacturered in mild steel and developed to be more about a loud sound instead of performance with the twin round tailpipes. We only recommend using this silencer up to approx 150ps as creating too much backpressure.

Supersport silencer supplied from 2000-2005

The Janspeed Supersport silencer for the MK1 Lotus Elise is designed to reduce weight and backpressure leading to increased power and stunning sound quality. This Supersport design was originally manufacturered for Lotus car in mild steel, Each Supersport silencer is now manufacturered by hand in high grade (304) Stainless Steel and comes with the market leading lifetime guarantee. New nuts and bolts are also inclusive for easy fitting. 8.7kg

After listening to many Lotus Elise owners and their comments we are pleased to now offer The New Janspeed Roadsport design silencers for all models of the MK1 Lotus Elise. Each silencer is beautifully hand crafted in nothing but the highest grade (304) stainless steel throughout production on individual jigs to ensure a perfect fit every time.
