Note: Information on this page updated Aug 2010!! These exhaust designs are specifically for the n/a models. The bore size is specific, as is the packing density and materials. If you’re planning a future Supercharged/Turbocharged install – you MUST upgrade the exhaust to a larger bore – 2.5”/63.mm.

I’m often asked how I, as a one-man business, have managed to avoid the droning/cracking problems being experienced by other larger, (much larger!) manufacturers. But, I did encounter these problems, the droning and the cracking, and I fixed them.

It’s called R & D.

Thru-Diffuser System Options:

Option A: 6”dia x 18”. This weighs 7Kgs. On the second cam, it has the most exciting F1-type scream I’ve ever heard on a road car. At 104 dbs, its days are numbered for the UK Trackdays. Perfectly liveable with on an everyday basis though.

Option B: 7”dia x 24”. This weighs 8Kgs. The future for any UK Trackday enthusiast. A drive-by reading of 92-94dbs. As with all my 2bular exhausts, this is a Straight-Thru design, so be assured, it still has a wonderful, deep, Sports-Car exhaust note. Perfect for owners who put in a lot of Motorway driving.

Option C: 8”dia x 22”. This weighs 8.7Kgs. This system, used on the more powerful supercharged installs,  is becoming very popular with the n/a owners – with an ECU re-flash and the increased power/cam change-over point, exhaust noise is increased to over 98dbs. On the second cam, it has the most amazing howl but at least you won’t be thrown off the circuit. It has a bore suitable for the n/a motor and is finished with the twin 3”dia tips. You don’t need to trim the heat-shield behind the number-plate but you do need to trim the front edge of the diffuser exit (it’s a lot smaller than the Exige S opening).
