Got a call from my dealer on Friday and Nissan approved the exhaust valve replacement and dealer has received the part, which is outrageously priced in Canada it seems according to what the service adviser quoted, near 5 figures! I checked online to see what the part is and number is 20150-6AV0A with a USA list price of $3236.57 which in itself is still outrageous but a third the price of what the dealer says the price is in Canada. There has to be something wrong with this whole pricing situation for this valve. The price in US for the entire muffler assembly with the 4 exhaust tips, the main pipe back to the mid-pipe and the valve is $4459.01, part number 20100-6AV0A, all parts with an asterisk being included.
Plus there is no difference in price for the entire muffler assembly without the valve as fitted to the Pure edition car, part number 20100-KB50A. Premium, Track and Nismo editions get fitted with the valve assembly. So in terms of muffler pricing, the valve is free as there is no price difference whether it is included or not in the entire assembly. Who needs it. It barely makes any difference in the sound anyhow.
How in the world can a simple exhaust valve and actuator be worth that much???
Anyhow my car is into the dealer tomorrow to get the valve replaced, first one my dealer has done (not that they have sold many 2017+ cars) but I will have to wait until I get the muffler really hot again to see if the problem returns. I hope not. My AMG GT-S has the same type of noise controlling exhaust valve and it has never failed in 3.5 years, and it makes a ton of difference in sound when open, making a real nice growl when open.
