There are options but there are no off the shelf aftermarket systems like this is a JC Whitney thing.
Here's an option from one of our sponsors, Mr.Fiat. "Original" GTS headers, whatever that means?
He wants $3,500 for each header. That's $7,000 for the pair. I suppose that he probably has the matching ANSA exhausts for something comparable but that is a presumption by me. I didn't ask.
I didn't realize they were that valuable? Who knew?
