1320 3" turbo-back Flange & Clamp V-Band Borg Warner S200 S300 Turbo Marmon 4.21"

This is the 3" Version (also 3.5")! Slip and weld groove is 3" OD (or 3.5")!

V-band Flange and Clamp set for the Turbine Exit (Downpipe side) on all the T4 flanged 200 and 300 Series Turbos, S, SX, and SX-E with the beveled face.

This is the 4.21" 3/4 Marmon Oulet V-band flange compatible with these BW (Borg Warner) Turbo models including:

Borg
Warner S200 S200-SXE S300 S300-SXE S200SX, and many others. This one
does not fit the S400 housings.

Exceptionally high quality 304 Stainless Flange

Machined from solid 304 stainless means it's extremely durable and corrosion resistant (no rust!). Welds very nicely to both stainless and mild steel tubing!

Has the special "contoured" flare (Borg Warner also calls it 4.21" 3/4 Marmon) to mate to the bevel unique to the only the Borg Warner outlet flange on all these Turbo models.

Has the nice 3" ID on the backside of the flange to slip the 3" (76mm) OD tube into and weld.

If you wish to use this on a 3.5" tube to build a 3.5" downpipe, just grind away the step and it's 3.5" ready!

Has a beefy dead section for warp free welding.

Use this flange and clamp to make a nice true 3" or 3.5" diameter downpipe! It's ALL stainless!
