ItWillBeSlow · 02-03-2021, 10:17 PM

After looking at the most popular options available (summit, speedway, JEGS, etc), it seems the 2.5" straight down manifold is the most widely available.

The outlet points straight down at the front cross member and it doesn't look like there is very much clearance.

Does anyone know if there are fitment issues with the straight outlet manifolds?

I haven't seen any angled back that have a coating anywhere, only raw.

Thanks
