anyone know what the stock exhaust manifold and exhaust system weigh? On my 6, the stock exhaust manifold is cast iron and really heavy 50+ lbs, so you can get some pretty decent weight savings on swaping it and the rest of the exhaust system. How about the 8?

 

I think someone said the stock was 52 pounds (catback exhaust). Dunno about the manifold, as there isnt really much else out there.
