Cars Muffler and Automotive in Redondo Beach. 310-371-7055 Tell them Steve from Justice Brothers sent you. They've put in lots of cutouts and probably could make some suggestions from experience.
On Artesia Blvd just west of Inglewood. They have been there 30 years and it's owner operated. Mike the owner does all the exhaust (his speciality) since he was a kid. He does a lot of the work for Edelbrock projects too.
They have awesome older cars in there constantly. I was in there today and they were rebuilding a Jensen Inteceptor and a huge mongo motor'd mid 70's Firebird. One the mechnics, Kevin, is doing a concours type resto/light mod on a 68 Charger.
