Too bad its only for Grand Prix'*.
It'* just 4 bolts bud, you could do it in the driveway in 10 minutes if you knew the bolt sizes...
But a lift is nice!

Bonnevilles have downpipes. It'* the pipe that goes from the rear manifold to the catalytic converter, there is also an integrated flex coupler at the manifold flange.

I'm gonna leave the rest of the exhaust how it is. You really don't need to change it unless you are running 12'*. The downpipe/cat is installed now. I took it on the freeway to test it out. Everything runs a lot smoother now. It'* not a huge difference, but I can see the engine running a lot better at higher RPM'*.
