RV Exhaust Manifold replacement

Perfect fit for replacement on our Newmar Mountainaire RV. The original exhaust manifold is known to crack at a weak point, Used lubricant on old studs the day before and installed this replacement on a Monday after work. Was pleased to find the gaskets were INCLUDED in the box! Made this an even better deal! Only had to purchase the turbo gasket and stud kit which were also available here at fridayparts.com ($11) attached photos show old vs new. Thanks Fridayparts for excellent service, well packaged products, price and fast delivery!
