MAP investment cast manifold w/ stock exhaust shield
Anyone have fitment issues with the MAP manifold and the stock heat shield?
i.e. bolt holes too close/far, need to trim heat shield, bottom mount point pokes out too much, etc.

Taken right off their website:
Features
- Meticulously optimized design yields a 22% average increase in exhaust flow over the OEM exhaust manifold with less imbalance between runners (check out our flow testing results above)
- Investment cast 310s stainless steel construction
- Factory heat shield provisions
- Includes (2) allen head bolts to ease installation of the manifold to cylinder head

If you're worried about melting a plastic valve cover with the MAP manifold and that's why you want the heat shield, then don't even worry about it. I have a plastic valve cover and the MAP manifold without the shield on it and it sits far enough away to not pose a problem.

On a stock turbo, this manifold will delay spool roughly 250rpm. I lost 400rpm of spool when I upgraded my stock turbo/manifold setup to a MAP cast manifold and a MHI 18k. Honestly I can’t tell the difference. To put it into perspective I lost 400rpm down low for an extra 1200rpm up top
