RC350 start up exhaust question
Hi all. I have a 2016 RC350 AWD with a muffler delete and I have noticed that when I first start it the exhaust has a louder raspier sound to it. After about 30 seconds the exhaust sound gets quieter.
I use to have a BMW Z4 which had a similar startup process and I found that there was a vacuum line on the stock muffler that you could pull and plug with a golf tee that would keep a valve within the system open making for a nicer sportier sound.
Does anyone know if the RC350 has a similar vacuum line or something else that would allow one to keep the raspier startup sound?

Interesting, I have not heard or known of that. Hopefully someone can chime in. Mine will immediately quiet down if you shift into a gear at start up, but I get what you mean it is a cool sound.

Its pretty typical for a car to have a louder or raspier exhaust note on cold starts. Here at the dealership (Lexus Dealership), every car we have (including stock RC's) has a bit more of an aggressive start when they haven't been started in a while. Im sure its all part of the warming up process.

My 2015 RC350 F-Sport when first started up will sound more aggressive, and quiet down after 30 secs to it's normal sound. As others have said it's part of the warming up process.
