1994 Regal Custom (L27 performance options?)

My brother has a 1994 Buick Regal Custom with an L27 motor (n/a 3.8L V6) mated to a 4T60-E (four speed auto with overdrive) and i'm trying to find out what performance parts are available for this motor/car.
I'm trying to find out if anyone makes headers for this car.
If anyone has any answers or any information regarding L27 performance then please post up and let me know.
It will be greatly appreciated.
Also, what suspension parts are available for these cars?

Thanks,
Charlie

There are NO performance options (other than custom stuff) for the L27. I have a '95 Regal GS with the same engine and I've searched long and hard for ANY performance parts with no luck.
