Default headers for s1
Hey guys, I have a quick question, will s2 headers fit on a s1, or are the exhaust ports different between the two? I'm guessing that the answer will be no but I'm hoping for a yes

If it is a no is there anyone out there that makes headers for a s1 3800?

thanks guys!

As far as I am aware the answer to both questions is no. Sorry you will have to port, polish, and ceramic coat your stock EM'*.

This L67 is going into a Fiero, right?

If so, www.westcoastfiero.com They have them.
