Thanks Teamzr1... I should have been more specific.
It's for a 2001 Targa. I was hoping that since installing an aftermarket exhaust system is such a common modification, there may be spare stock systems taking up space in garages.
If it fits then I think that a Z06 system would work for me (I understand that it still relatively subdued), but I was hoping for a lower-cost option
Many thanks,
Bill
