So Google says it is 3" pipe.
What I am gathering from your post is that it gets reduced to 2.25" somewhere around the resonator?
M6G (this site for the S550) says the S550 is 2.75" with a half inch neck down to 2.25" at the "muffler bottle neck"...
Ok, I am not following. I guess I do not know enough about the exhaust system (my car is too low to crawl under there and look), and you wrote that you "added a larger 3" muffler."
Is this an additional muffler, so now you have the resonator, a muffler, and the stock mufflers?
Sport and Track are definitely different at times when just driving, and Track leaves those valves open constantly, which becomes annoyingly loud. Sport does not do that.
There is a huge difference when driving slowly up my driveway between track and quiet, because I use those two as a demonstration to my 11 year old daughter, who always complains that Daddy's Mustang is too loud, that, indeed, I have made it quieter. I put it on Track and say, "Listen," and...
Did you lose the active exhaust when you "added a larger 3" muffler?"
I had no idea the exhaust necked down to only 2.25".
That second clip was pretty quiet. Surprisingly so.
Just so I am clear, your exhaust is stock except headers, no cats, and a larger muffler? But you retained the stock...
So I saw a lot of speculation about using a Whipple this time with more horsepower.
I have not seen any updates.
Does anybody know anything more, like, for instance, did they drop their time down?
If I were to install Kooks 1&7/8" long tube headers on my car, will it sound terrible?
I actually like the sound of my Dark Horse right now.
I read dismissive comments like, " Great way to add only 20 horsepower and make your car sound terrible at the same time."
Will they make my car sound...
In some conditions of throttle Track and Sport are the same. In others, not. Sport varies the valve in the exhaust. Track just holds it open no matter what.
Are these particular tires or generalized?
I ask because even within the same manufacturer a different tire of the same size, say, 315/30zr19, can be greatly different tread width and diameter.
That link was very helpful, thanks.
I guess I am just shocked that I can cruise the interstate with -2.5° of camber without wearing out the inside of the tread. Maybe I will make this change and drive around like that on the street - them maybe look to get more adjustment from aftermarket...
Did you try it in Drag Mode, as he suggested? It's ok. It does not mean you have to be wearing women's clothing. It is a mode selection on your dashboard that changes some of the settings, maybe including this driveline protection tuning. Try it out.
