2 GTOs

I am looking for the pipe between the stock manifold and stock muffler for a 2004 Z06 (I actually only need the section between the manifold and cut as close to the CAT as possible).

Also happy to take recommendations for an exhaust shop in north NJ area that would be willing to build one without CATs. Fully caged race car with SCCA and NASA logbooks, never been street registered as far as I can tell, but no one wants to make an exhaust without cats. Headers are not an option for my class, OEM manifolds only.

Thank you
