NPP Exhaust / Fuel Mixture Question
Here's maybe a dumb question, with all four open what happens to the fuel/air mixture? Does the fuel system take care of it if it's leaning out? I've got an 09 coupe and run them open most of the time, just curious.
Thanks!
Thanks!

No problems.
With the NPP open, very little exhaust makes it's way through the quiet side, you really only run through 2 tips at a time. You may notice that the NPP tips tend to get quite a bit blacker than the quiet side tips. That's just because the fuel mixture is set rich from the factory and when it all goes out through the straight NPP pipes it deposits more.
