No, sorry I don't.
It is pretty easy to do though.
You just remove the factory pipes and install the aftermarket pipes providing the tubing size matches.
If it does not you will need to replace the remaining exhaust to match the size or use pipe reducers or increasers to match the tubing.
The worst part is getting old piping to come apart.
Sometimes you can tap around the joints with a hammer or heat them with a small torch to facilitate their removal.
