Note: These exhaust designs are specifically for the Supercharged Exige S/Elise SC models. The bore size is specific, as are the packing densities and materials. If you’re planning further tuning, or racing – please talk to me first!

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/240Cup 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.

The large, open chamber in the 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 it’s quiet on cruise, so you can still have a conversation/phone call at motorway speeds.

If you’re planning further tuning, re-flashing the ECU or fitting the Sports Cat/2bular 4-1 header, I would strongly recommend fitting the 8”dia system for best noise control.

A 2bular Thru-Diffuser exhaust design, featuring the popular 8”dia system. Owners looking for a Sports Car sound with no drone and discrete noise levels at Motorway speeds, this is the system for you. A re-designed layout, means there is no cutting/profiling of the numberplate heat-shield required. The oval tip exits the diffuser panel same a std. You keep the rear grilles in place, the car looks like std, but now it sounds like it looks! A 2.5”/63.5mm bore system, when run with the std Cat will pass the noise limits at Bedford.

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!
