Well CTS seems to have a bolt on one for $250
Sounds stupid, total waste of money, don't do it.
ok but wooooopshhhhhh
why would it be stupid
Because that one doesn’t sound. Good
oh
well how much would a decent sounding one be
Si
and would that be any harder to install or anything
Ummmm that I don’t know 100% so I’m not going to suggest anything not having a “Professional” Opinion
