PERFORMANCE:

These 2bular exhaust designs are specifically for the Supercharged Exige S/Elise SC models.

If you’re planning to fit ANY aftermarket exhaust system to these cars, it HAS to be a straight-thru design of the correct bore for best power and (arguably) best noise! For the Performance Pack/Cup cars, the 2bular system is a full 2.5” bore. I know of at least one manufacturer whose system appears to be 2.5” but inside the silencer, it’s only 2” – shocking.

NOISE:

The large, open chamber in the very heavy std system wipes any character from the exhaust note.  By comparison, a straight-thru design, like the 2bular,  has a wonderful exhaust sound; a deep, bassy note on acceleration, rising to a real howl at the top-end but with the 8”dia 2bular, it’s quiet on cruise, so you can still have a conversation/phone call at motorway speeds.

It’s interesting to note the difference between acceptable levels of exhaust noise here in the UK and with some overseas markets. In the UK/Europe, the 8”dia system is almost universal. In the USA, it’s the 6”dia – the 8” is too quiet for most ears over there. Running a De-Cat Pipe dramatically increases the noise levels – you wouldn’t get near a UK trackday with one fitted.

LAYOUTS Thru-Diffuser Systems:

8”dia x 22” Oval system;  Owners looking for a Sports Car sound with no drone and discrete noise levels at Motorway speeds, this is the system for you.  The rear grilles stay in place, there’s no cutting/profiling of the numberplate heat-shield required. The oval tip exits the diffuser panel same a std.

THE CAR LOOKS LIKE STD, BUT NOW IT SOUNDS LIKE IT LOOKS!

This system,  when run with the std Cat will pass the noise limits at Bedford.

I am sometimes asked to make a Thru-Diffuser system for the supercharged installs with the 111R twin-tip tailpipe layout, I can do this but it adds an extra 1Kg (2.2lbs) and costs an extra £24 + Vat* Lead time: 2 weeks for the Oval tip, 3 weeks for the twin tip.

In the pic below are the two 8” systems; the 22” long, Off-set Thru-Diffuser and the 24” long, GT3 Single Tip. Thanks to the use of lightweight pipework on the Thru-Diffuser design, they both weigh the same – 7.7Kgs.

For comparison, the smaller 5”dia, Lotus Stg2 n/a system alongside, weighs 8.1Kgs!
