Does anybody know if the loud exhaust increases the fuel consumption?

 

Typically loud exhaust goes hand in hand with a heavy right foot, which equates to more fuel consumption.

 

The bangs on the overrun are definitely caused by deliberate over-fuelling. Do you seriously care? It's one of the cheapest smiles I've paid for :-) My V8s is doing better gas mileage than my BMW 650i and is a good deal more powerful. I think that the exhaust sound itself isn't really using significant fuel, but it does encourage me to drive in a way that isn't necessarily so.... efficient. But the car is there for fun so I'm not going to lose sleep over it.

 

It is more curiosity than anything else!

 

i know gas prices in greece are outrageous but thats not something you can think about after buying an f type

 

You could argue that louder is less restrictive and more fuel efficient assuming you drive the same way.

 

I'll chime in, I have an amazingly loud exhaust which I put on at the same time as the pulley and tune and my fuel consumption seems to have gone down slightly (to under 11l/100km). So if I keep the car for about 113 years, the fuel savings will pay for the work that I had done.

 

Of course!
I do agree!!

 

haha
Sure!!

 

Our friend is in Doha, the capital of Qatar.
Which has cheap petrol/gas, even cheaper than the US, see here: https://www.globalpetrolprices.com/Q...soline_prices/
Not jealous much as here in good ol' South Australia right now the price of 98 RON for my F-Type is around $9.00 AU per gallon!

 

Unfortunately, most cars don't work that way.. The ECU mapping rarely (if ever) auto adjusts it's mapping based on the exhaust volume.

 

No, a louder cat-back will not have any affect on mpg.

 

Disagree - you'll be using the loud pedal more, so you'll use more fuel

 

I haven't thought about this! Good point!
