On initial start up the sound is ok but soon drops, anybody looked into keeping the valve open ?

It sometimes does sound like there is a valve on the exhaust but I'm pretty sure there isn't - can't see it on any of the pics.

The optional Sport exhaust has a valve iirc.

QuickSilver have a solution:

From Motor I........I assume this applies to the 720 as well.

At its highest wail, the titanium part makes the Sport Series models five decibels louder than the standard exhaust. In part, this boost in sound comes from the construction that removes the mufflers and resonator. McLaren tunes the pipes so that the tone at low revs is a pleasant burble. Above 5,000 rpm, the noise really starts growing in pitch. Imagine how wonderful this would sound from the cockpit of a 570S Spider with the top down.

The switch from steel to titanium also brings a minor performance boost. The lighter metal means that a Sport Series model weighs 10.6 pounds (4.8 kilograms) less with this exhaust in place.

No, the article you quoted is for the MSO exhaust version for the 570, this is a third iteration in the line up, standard, sport and MSO, the MSO looks a great bit of kit but again no valves.

A 720S MSO exhaust would likely be on my shopping list but there is no talk of availability or even if it is definitely being developed.

I had seen this one below before from a German tuner Manhart but there is no info on it other than the pic it looks very similar layout to the Maclaren Accessory one.....

That's the same exhaust as fitted to mine, definitely got valves in it.

Ooening thr values makes no difference in noise mate. Tried it. The reason why the car is louder when you first start it up cold is the it’s just revving higher which soon settles down.

I’ll let you know next week how I get on with the full capristo set up

It has the loud start, turn ignition on without pressing brake pedal, put the active thingy on, track-track then press brake pedal and start. It starts up with higher revs although mine only does it every now and then, bit hit and miss.

Ted, how do you know have you seen them, can you share a pic of them ?

Is your a factory sport exhaust ?

I asked the question about availability of an MSO version but whilst they are considering it there is no time frame.

MSO exhaust is ages away. There are lots of options for alternatives though so no need to stress

Mines got the sport exhaust, shine a torch down the end of the pipe and you can see the valves.
