I'm wondering if I need to get exhaust manifoldheat sheilds for my 3800. It had them when I bought it but they were in bad shape, so I threw them out. Do I really need them or can I run the exhaust fine without the heat sheilds?
W-body 3800 cars (Impala, Monte Carlo, Grand Prix, Regal, etc) will have the heat shields. C/H/G body cars will not (at least I've never seen them on one of these cars).
FYI the front cast iron exhaust manifolds are the same for all 3800 equipped FWD cars. The rear tubular steel manifold is different. W-bodies are different than what was used in the C/H/G body cars.
Also important to note that GM changed the way the heat shields were held onto the manifolds on Series 3 engines. So a set of Series 3 heat shields may not work on Series 2 manifolds.
