LS1 Vibration
I'm running an 2000 LS1 in my Olds and I am also running stock headders into a set of Flowmaster 40's and that's it.
No cross pipe or Cats.
I notice that at anything over 4K rpm the car feels like it has a viabration.
It kinda feels like the entire exhaust system is bolted directly to the frame.
You can feel it in the seat of your pants.
The engine runs fantastic and gets great mileage but I'm wondering if
there might be some things I could do to reduce the "oscillation" or viabration...
It doesn't feel like anything is out of balance, it's more like a "buzz" at high rpms

did you change the transmission from what was connected to the engine when it left the factory? the RPMs seem to be too high to be resonation but aren't the flowmaster 40s the very deep, loud ones?
