D2 S8 - Big end gone?

[dhrf]

I remove the cats, and put 2 2.5inch tubes all the way to the rear silencer.

I did it in diferent steps, first the cats, 1 was tottaly bloked, the car run better and fuel was half it use to eat.......so 2 big tubes all the way to the rear.

A lot of noise , much more fuel economy, and run like it have 40hp more.
