Custom Build full system


Based on our GT3 race cars, full race system with 100 cell race cats.


Fours years in development and based in no small part to our GT3 race cars we are delighted with our new race system, we wanted to get it absolutely perfect, perfect tone and sound – not too loud for track days but the right pitch to make you feel like you’re driving a screaming V8. At lower RPM the car rumbles and barks but at higher RPM the pitch changes to a higher octave and literally demands you push harder and harder – its really is addictive. There are no valves on this system, why bother, get the pitch and tone right and you wont need a quieter/louder version – just the right sound all of the time.

Noise is nothing without power however so gaining at least 15-20bhp was the minimum we wanted and we achieved that, however more is available by adding our race manifolds as the two parts were developed together, again using the GT3 cars as templates, especially for the manifolds; we spent a long time getting the length of the primaries right and making sure a wider bore could fit in the relatively small space available.

A lot has been discussed about carbon fibre tail trims and its true, its very hard to get these right where the carbon can withstand the heat from the exhaust and our trims are perfect. Each of the 4x85mm tips has a TMS devil logo on and the laquered coating is protecting rather than trying to be shiny. We did 25 back to back dyno runs testing the carbon tips (they wont get hotter) and the tips look as good as the day we fitted them and even in full runs they can be held by the bare hand – they work that well.

Cat specification was crucial, no engine management lights and no need for wireless kits to turn off management lights – all that shows is that the cats used are not of sufficiently quality for the S65 engine management system to deal with. We also chose stainless steel as the material and not titanium, titanium is very light but its brittle and whilst saving weight is a good thing an extra few kg less when its slung underneath the car is not something that is that important – up high on the roof – yes but underneath the car, right near the floor? No, its excessive and we were keen to make sure the system was affordable without compromising on power or sound.

The full system comprises everything from the manifold back, 100 cell race cats, centre section with cross over pipe, rear silencers and quad carbon fibre tips

Fitting takes most of a day so allow for that when booking and as you’d expect there is a full TMS warranty on the full system which could last a lifetime.
