| Re: why no aftermarket for cts?
There are performance upgrades all over the net.
You just have to do the right search.
Broaden your search by remembering that Cadillac was not the only vehicle powered by a HF/AlloyTec. Which started it's design over seas, and is shared by many Holden/Vauxhall cousins.
There are even free horsepower being found for these engines.
A larger bore TB has been done, headers are made(but may need to be modified to fit 'Caddy), PCM upgrades, ported intake manifolds, performance oriented spark plugs, upgrade mass air, etc.....
Suspension upgrades are out there as well.
As for body mods, anything can be done with a little elbow grease or contacting the right shop.
