I'm sometimes asked for a LOUDER system than the factory exhaust - or a LIGHTER system for the track. I much prefer to build lightweight race-style systems for the real enthusiast. NOT TITANIUM - that material is unsuitable for Lotus installs. The scream from this exhaust at maximum revs is seriously hard-core but you can drive through town/suburbs without attracting undue attention. It uses a unique internal design eliminating the usual fibreglass/wire packing materials used in performance silencers. There is no dronnnnnne.

If you look at the exhaust valve on the factory exhausts, you'll see that Lotus has gone to some trouble to position the vacuum chamber away from the silencer - HEAT is the enemy. I decided the best strategy was to remove that valve AND its associated pipework altogether. Losing 6Kgs is always a good move!

So, that's no packing materials, no exhaust valve or pipework and using a smaller silencer with an 8" x 5" (200mm x 125mm end-plate) brings this system down to the factory Titanium exhaust weight! THIS SYSTEM IS NOW BEING RUN IN THE LOTUS CUP EUROPE SERIES.

IT IS NOT SUITABLE FOR THE UK TRACKDAY MARKET!

The tailpipe module with its beautiful merged collector is connected to the system by a V-band to allow full adjustability in the diffuser aperture.

SUPPLIED WITH ITS OWN DE-CAT/LINK-PIPE TO THE FACTORY DOWNPIPE. I USE A V-BAND CONNECTOR TO THE SYSTEM. 

TAILPIPE OPTIONS FROM: 100mm diameter CARBON, TITANIUM or STAINLESS -
