Custom Build Full Race System


Custom build full race exhaust. Here it through a tunnel!


The full race exhaust comprises of our catback system (so you can buy it in stages) as well as a pair of cat replacement sections. We have designed and specified our own cats for these cars, 200 cell but with a 72g coating means no engine management lights and maximum power.

The 12c/650s standard system has its first, 400 cell cat mere mm from the outlet of the Borg Warner turbo, thats not great for power so we created a custom flange (Borg Warner will only sell theirs to Mclaren) and then extended the distance to the cat by 15cm. We then add our own specification cat and then straight through the pipe to connect with the catback section at the top of the engine bay.

Standard exhausts are surrounded with heat insulation barrier so we get rid of that and then Zircotec ceramic coat the entire section. Ceramic coating is the best way of dealing with heat, it literally means the heat is kept inside the pipe and exits the car and not heat the engine bay. We only use Zircotec and we only use their highest level of coating and even the highest specification colour, if you want gold then go right ahead but you’ll drop the ratong 30-40 degrees, so we only spec the grey/black – the highest coating level possible. Once all the panels are on you cant see it anyway!

We then mount the system to our catback where we ditch the silencers, widen the bore and redesign the system to allow for faster airflow via a X pipe custom welded with mandrel bends to ensure maximum internal diameter for airflow.

The sound is awesome, indeed it is the loudest exhaust we have ever made on this car, it is very ‘in your face’ and not for the feint hearted. If you need it a little calmer then we add a small rear silencer into the rear section, recommended for Spider owners or those going on the quieter tracks.

As with all of our custom build exhausts we only use type 304 stainless steel , we only use mandrel bends so the interior airflow is maximised and all are covered by our lifetime warranty, each exhaust is hand built to the car by us in our workshops – we dont just bolt it on (which means the cost includes labour to fit).

Price includes labour, which is extensive to fit so if you ‘d rather buy an off the shelf system be aware that fitting takes 16 hours! We have to:

Remove rear airbrake
Remove all undertrays
Remove top covers
Remove all rear grills
Remove all rear brackets
Remove rear deck
Remove rear heat sheilds
Remove exhaust
Remove air pipes
Remove OEM cats

Then replace it all again.

All of this is included in our price as is the Zircotec coating for the cat section, this alone is £850 and is included.

Price is to use the standard car exhaust tips but we can add any number of ideas here from carbon fibre , titanium and steel, the World is your oyster (but at extra cost).
