TMS Sports Exhaust


Want better sound from your 650s? Fit our custom build sports catback exhaust


It is simple enough to buy an off the shelf exhaust for the 650s, however in our experience quality is so variable that we are unwilling to risk our reputation in supplying an off the shelf system so we only offer our own custom build exhausts. Custom build means exactly that – fully hand built in house at our workshops near Silverstone, nothing is pre-made, we design, develop and weld the entire system from scratch, in front of your eyes if that interests you.

We only use the highest quality type 304 stainless steel, this means no rust, ever which is confirmed by our lifetime guarantee on the system, we stand by our exhausts not just for the first owner but for the life of the car.

Our catback for the 650s was developed on our own 12c over two years of research and work. The sound is simply incredible, if you think the Mclaren sports exhaust sounds good then be prepared to be blown away, we even fitted a Mclaren sports system to a customers car and started it up, he loved it, but when we started our own car next to his his face dropped and immediately asked us to take the Mclaren one off and fit one of ours, he sold the Mclaren sports exhaust for for than ours cost as well!

The catback system is exactly that, the standard cars cats are unaffected so there are no changes to fueling so no issues on warranty – its represents the same part that Mclaren change with their own sports exhaust (our simply sounds better) so there are no warranty questions. Obviously the Mclaren warranty wont cover the exhaust itself but thats covered by our lifetime warranty so you’re fully covered.

The system is fully mandrel bent (means the internal diameter of the pipe is smooth and uniform) , 3″ bore (essential for the power level of the 12c) and features our unique cross over design to ensure pressure balance between the banks of cylinders on the Mclaren engine. The sound is stunning but perfect for track use, we have tested the exhaust at Brands Hatch, Donington, Silverstone and even Castle Combe – all passing noise limits without issue.

Tip choice is entirely up to you, you can chose to retain the standard tips to retain the stock look, single outlets like the 675LT or quad pipes as fitted to our own car (there is a slight price adjustment for 4 x carbon fibre tips), we can even do a loveheart tip if you like – however it looks dreadful!

The price includes full fitting which is a job in itself, fitting an exhaust to a 650s means the under trays have to come off as well as the top panels – if you dont know what you’re doing you can easily interfere with the air brake function which will require a trip to dealer to fix – working on Mclarens demands direct experience not google searches. Enhance your 650S with the best exhaust possible.
