hmmm.. can't even tell which is which? Would need to hear revved to redline and preferably under load in gear, not just in neutral.
im an old git and i can tell its the silver one with sports,still glad you dont think its too much difference i dont feel too bad about not speccing it!!

okay I took another listen and I can hear some difference in pitch and intensity. However, would really like to hear a real world drive-by up to redline and see if that "metallic" timbre previously discussed indeed materializes. Also, there is the consideration of how does it sound inside the cabin, as we know some exhaust noise is piped in.

.. it does. I ve heard it on video side by side with standard. I would get the sports exhaust hands down. It has flaps so you can chose it to be quiet or abnoxious. This is the one "emotional" extra that mclaren developed (een though I am sure it also makes some power/torque)

I definately asked if there was a power or torque gian when i specced,and was told it made no difference,or i would have had it

I assume like the ferrari the valves do not open until 3500-4000 rpm.

So just giving it some gas under no load to 4K wont really make that much sound diff.

Open the valve and I am sure big diff.

Or do like 99% of ferrari guys do including my self pull the rubber hose and plug it. Then valves are open all the time.

• Sport Exhaust is louder and produces a more ‘racy’ sound
• Weight difference between Standard & Sport is negligible but the Sport Exhaust is lighter (2.4kgs)
• The Sport exhaust will give a louder internal noise, however thanks to the ISG, comfort and refinement at part throttle/cruising conditions is maintained
• Standard exhaust produces 100dB(A) static (measured at 45 degrees, 0.5m @ 4000rpm)
• Sport Exhaust produces 104dB(A) static (measured at 45 degrees, 0.5m @ 4000rpm)

Whilst I am firmly in the McLaren camp, I must admit that the sound of the 458 in the EVO video takes some beating.

...considering that every 3 dB is effectively a doubling of apparent sound volume, the sports exhaust is seriously louder!

I can't tell the diff. I guess I should get it. I am cheap as over here tax is 115% on all so I am trying to just get the Macca plain vanilla.

Scary as it maybe it's already over 1/2 mil USD 520K USD with nothing!

I hate to say that the FEZZA has CCB as standard on Cali and 458 and Macca doesn't put it on... at this level, it should be standard...

Yes that's what all manufacturers say when valved sport exhaust is an option but it simply is not (and can't) really be 100% true. When you bypass the silencer (or mixing box for the mp4) then you effectively reduce backpressure. This is very good for a turbocharged engine as you get less backpressure for turbo spooling and ultimately boost. The bosch ecu works with torque limits so you effectively reduce that effect but you ll always get better engine response and torqu with less backpressure.
On a carrera s the PSE option was measured independently at +13hp and 20nm torque while on my turbo (added aftermarket) it was measured around 25hp/50nm.
But then you also have the temperature advantage and weight advantage, both important for this car.
Finally if there 1 thing that all testers said is the bias of this car towards the "less" emotional side that perhaps was a tad too much? Well if you are on that camp then this option should be definite tick imo.

what is a problem for me :
"Track day applicability

Most tracks will have certain noise restrictions for vehicles. However, these do not just vary from country to country, track to track but also from event to event. As an example, Councils in the United Kingdom follow guidelines laid down by the Motor Sport Association (MSA), the basics of which are a static limit of 105dB measured at ¾ of max power rpm half a metre from the exhaust at a 45 degree angle. However, often stricter rules are implemented. Drive by limits tend to be dependent on the specific event and can be measured in different ways but is often at a 20 metre distance at a point of acceleration (long straight). In the UK, both standard and Sport exhaust will be eligible for most trackdays.

Regulations in other regions usually tend to be more lenient but we advise each retailer to investigate local track restrictions in detail."

Is that tax on cars only or also on all parts you import and fit later on?
tax on cars and all options. unless you fit it on after 6 months but people seldom do that for supercars as they order factory made and seldom retrofit same for F. It's crazy money.
