I'm looking to run dual T4 S366 on a forged 347. There's only room for 3" downpipes. How much back pressure/how many issues is this going to cause? I'm shooting for 850-950whp tops, not trying to break any records here. But I don't like the idea of building an inefficient setup.

Thanks.

Shouldn't be an issue. Maybe step up to 3.5 if it's within a foot or two of the turbo

890whp@23psi with dual 3's to a single 4 full exhaust (which on paper flows less than dual 3;s). You sould be fine. Never dyno'd it without the exhaust on to see if there was a difference though.

3" downpipes will not be any restriction for what you want.

I run similar turbos (Garrett 67s with p-trim wheels) and had no issues on 3" dp's on a 6.0.

Made 806rw on 14psi 1st tune up on car, lots left!
