Is this just for headers build data or entire exhaust system? I'll take a chance it's for complete exhaust system as I have to figure out how to fit undercar exhaust and tailpipes on my ERA. I don't need to be trying to fit any larger dia. pipes under there than I have to.

bore size (4.145), crankshaft stroke (4.25), rod length (6.70), peak hp rpm (around 5300 to 5500 - very flat), comp ratio (9.0)

intake data : valve head diameter(2.09), valve lift (.563), dur. @ .050 (231), degreed centerline (108 intake cernter line), lca (lobe separation - 112)

exhaust data: valve head dia. (1.65), valve lift (.575), dur. @ .050. (236)

Thanks
