hey ' bob nissan ' - is it for that same old sil eighty hatchback with the big heavy motor i'm thinking of

is that ' piece of crap ' dumb heavy cast iron exhaust manifold holding you back ??
have you thought about giving burns stainless a call for the collector and what not ?/ maybe do a slip fit style setup, talk to the supra guys or something??
i love that 'na ka's' sound. it sounds so special
